Duct tape will melt at around 200 degrees F.
How do we test hypotheses?
by collecting data. Experimentation In our experiments we attempt to set up conditions so that we know that the outcome of the experiment is the result of the variable that we are manipulating. I hypothesize that a given substance will have a positive effect on plant growth. I will set up several experimental conditions, holding everything constant in each group except the substances given for growth. I observe the growth of the plant, and draw my conclusions. The hypothesis may hold, or it may need to be modified. For example, I notice that the substance that inspired the hypothesis may have caused growth that was too fast, leaving spindly and non-productive plants. I may want to continue the development of the substance, or perhaps find a way to blend it with other substances, and then continue the experimentation. _______________ Here is another example: I am investigating the properties of water, and I need to know all I can about how water, ice and heat interact. I know that when water gets cold enough, it freezes, and that when ice is exposed to heat, it melts. I might come up with a hypothesis-- a first attempt to understand what is happening with water and ice. I hypothesize: Since water is the liquid state of H2O, and liquids are warmer than their solid forms, water must be warmer than ice. It must be that as soon as water forms from melting ice, it is at least a little warmer than the ice. After all, at zero degrees water becomes ice. At this point, I do not know for sure, but I am speculating (hypothesizing) based on the general information that I have. I wonder how I can test my hypothesis: Let us assume that I can measure the temperature of ice and of water with great accuracy. I should be able to easily make a mixture of ice and water, while measuring the temperature of each independently.If my hypothesis is correct, I will find that at one atmosphere of pressure and in a chamber kept at exactly zero degrees Celsius the ice will warm to zero degrees Celsius (if it starts out colder than that) and it will get no warmer. When it is warmer, it is water and not ice.I will also observe that the water will be at least a little above zero degrees Celsius when it first melts away from the ice.I apply heat to the ice and some ice melts.To my surprise and annoyance, I find that the water is exactly zero degrees Celsius. We have a problem. My fellow engineers need an answer, and I've been hyping my hypothesis all over the place..... Eureka! I have found it! Keeping the chamber at zero degrees is the problem; as soon as the ice melts, the chamber air starts to cool the water, and it must also be cooling the thermometers, leading to an experimental error in the readings! I'll keep the chamber at 5 degrees Celsius.... I go back to the lab and I notice that my containers now all have a mix of ice and water, and the chamber is at exactly zero degrees Celsius. Not only that, all the ice is now at zero degrees Celsius, and so is the water! Exactly! Now I am just plain confused. I leave the chamber exactly as it is for several days and nothing changes. Everything in the chamber is verified to be at zero degrees Celsius, water is not in the process of freezing, and the ice is no longer melting. It just all stays in equilibrium. If my hypothesis had been correct, there would be no water in the chamber, because supposedly at zero degrees Celsius all water is ice, and "water is [so I hypothesized] always at least a little above zero degrees". My hypothesis has tanked; time for a new one. I wonder and wonder, and spend a few sleepless nights. Then I realize-- it has something to do with heat; it must. It has something to do with adding or with taking away heat... Hmmm. Testing a hypothesis is something like that. You wonder, and you explore. Hypotheses develop, and may become well-known theories when they seem to be able to withstand test after test designed to expose them false. When you think about it, how would you develop an experiment that exposes a hypothesis as true? They would be the very same tests, with results that support the hypothesis. Reality determines the outcome, not really the 'test'. A silly or inconsequential test will still show results in support of reality. But as mentioned above, even if all completed tests support a hypothesis, that is not to say that some unexpected approach will not be applied tomorrow.
What can provide a temperature rise of 40degrees Celsius?
The only way to increase temperature is to apply energy. e.g chemical energy in burning fuel, electrical energy by turning on an electric fire, friction energy by rubbing things together etc.
What is the unit used to measure angels and temperature?
Degrees is the measure for angles and temperature. "Degree" can apply to many things other than angles and temperature. In fact, a degree of angles is quite different from a degree of temperature. You might say more exactly that there are degrees F, degrees C, and degrees K acting as units of temperature measurements, in fact. Also more precisely, you might say that there are 'degrees of arc' as the unit measure of angles. But then, so are 'minutes' and 'seconds' a measure of arc - smaller units of a degree.
Which statements apply to food?
Do your own work ! By asking these questions on google you're not learning anything ! At all !first , that was very rude, second storage medium for energy and release energy during decomposition, I'm sorry for rude people like that, I kinda pity them sometimesI hope this helped ^^OWNED!!
Can water stay liquid below zero degrees Celsius?
Yes, water can stay liquid below zero degrees Celsius. There are a few ways in which this can happen. The freezing point of water drops below zero degrees Celsius as you apply pressure.
Which statements are true about a block of ice at -10 C as you continue to apply heat?
The ice is melted after 0C.
What is 0 degrees Celsius in Fahrenheit?
0 °F = -17.78 °C0 degrees Fahrenheit is -17.778 degrees Celsius.Scroll down to related links and look at "Conversion of temperature units".Temperature is easy to convert from Fahrenheit to Celsius yourself. You can use the formula Tc = (5/9)*(Tf-32) where Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit. 0 F is -18 C.0 degrees Fahrenheit = -17.78 degrees Celsius.
What does doubling the energy content do to temperature?
This will depend on what kind of temperature scale you intend to use.Degrees Celsius, Degrees Fahrenheit or Kelvin.Celsius:If we have a positive number, say 10 degrees Celsius, then we would get 20 degrees Celsius.If we have a negative number, say -10 degrees Celsius, then we get -20 degrees Celsius. It will simply be twice as cold.Fahrenheit:Exactly the same rules apply as for Celsius in the examples of Celsius.Kelvin:Kelvin is an absolute that is "only" dealing with positive numbers.double of 10 Kelvin is 20 Kelvin. Double again and we get 40 Kelvin. Easy as pie.Temperature indicate how much energy there is in an object or a mix of objects.When doubling the temperature in Celsius, we add to this energy.When doubling the temperature in Fahrenheit, we add to this energy, but not as much as we would in Celsius.When doubling the temperature in Kelvin, then we actually double the energy-content. Much more than when using either Celsius or Fahrenheit.Increased temperature mean increased speed of reactions.

What statements is not true for AC?
Ohm's law does not apply to AC circuits.
Which of the following statements apply to the Old Kingdom?
The pyramids at Giza are built.
What is 35.3 celsius in Fahrenheit?
To convert Celsius to Fahrenheit, you apply the following formula: f = c x (9 / 5) + 32 Replacing c with 35.3, you get 35.3 x (9 / 5) + 32 Which is equal to 95.54 degrees Fahrenheit.

How to heat 5.25g of water from 5.5 Celsius to 64.8 Celsius?
Put it in a container and apply heat to the container.
What formula should you use to convert a celsius temperature reading to a Fahrenheit temperature reading?
Apply the Fahrenheit to Celsius conversion in revers: Multiply Celsius temperature with 9 and divide it by five. Then, add 32 = Fahrenheit temperature.
