If one pound of water is at a temperature of 32 degrees Fahrenheit, how many BTU’s must be removed in order to create a block of ice at 17 degrees?

LATENT HEAT OF FUSION

When one pound of ice melts, it absorbs 144 BTUs at a constant temperature of 32°F. If one pound of water is to be frozen into ice, 144 BTUs must be removed from the water at a constant temperature of 32°F.

What is the state of sodium at 1000 degrees Celsius?

It depends on what temperature scale you are using.

For Celsius (ºC), Sodium is has already melted and will be in liquid form.

For Fahrenheit (ºF), Sodium has not yet melted and is in solid form.

What substance in the upper atmosphere is important to temperature changes in the upper atmosphere layers?

it is the ozone layer in the atmosphere because it is what keeps the atmosphere in check of what is happening in the atmosphere.

Is 64 cold,hot or worm?

64 is considered warm. It is not cold or hot.

Would you rather drink a cold milkshake in the cold or drink hot chacolate in the hot?

Well in my opinion, I would drink a hot chocolate in hot areas because you won't really be feeling much heat if it's hot since you don't want to drink something in one go otherwise it will burn so the hot chocolate will turn cold soon anyway.

What is data logger?

Temperature is measured with thermometers that may be calibrated to a variety of temperature scales

What Temperature and pressure combine to keep the outer core in a state?

The temperature of the outer core is estimated to be around 4400–6100°C, and the pressure is estimated to be around 1.3 million to 3.6 million times atmospheric pressure. This combination of high temperature and pressure keeps the outer core in a liquid state.

What does copper oxide produce at high temperature?

Laboratory preparation of copper oxide:

  1. copper salt such as CuSO4 reacts with alkali (NaOH) to generate Cu(OH)2, and then Cu(OH)2 is decomposed by heating to prepare CuO.

  CuSO4+2NaOH==Cu(OH)2↓+Na2SO4

  Cu(OH)2=△=CuO+H2O

  1. Heat copper (Cu) to make copper react with oxygen (O2) to generate oxidation

Copper (CuO).

  2Cu+O2==2CuO

  1. Copper oxide can be prepared by heating metallic copper in air or decomposing copper hydroxide, copper nitrate, basic copper carbonate, etc.

HOW TO Enumerate the approximate temperature equivalents when an electric furnace is used in ignition.?

To enumerate approximate temperature equivalents when an electric furnace is used in ignition, you can refer to the specific heat settings or temperature ranges of the furnace. Generally, electric furnace temperatures can range from around 600°F to 2200°F depending on the type and model. It's important to consult the manufacturer's guide for accurate temperature readings.

What Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.?

The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.

A substance that evaporates at room temperature is described as __________. What word completes the sentence?

Ah, a substance that evaporates at room temperature is described as volatile. Just like the joy we feel when painting happy little trees, some substances can't wait to turn into a gas and float away into the sky. Remember, every detail in nature has its own beauty, even the ones that like to disappear into thin air.

A gas has a temperature of 14 degrees C, and a volume of 4.5 L. If the temperature is raised to 29 degrees C and the pressure is not changed, what is the new volume of the gas?

Using the ideal gas law, PV/T = constant, we can find the new volume. Given that the initial volume is 4.5 L and the initial temperature is 14 degrees C, we can calculate P1V1/T1 = P2V2/T2 to find the new volume at 29 degrees C. Solving for V2, we get V2 = (P1V1T2)/(P2T1). Substituting the values, we find the new volume to be 4.62 L.

Why is the inner core in solid state despite the high temperature?

The inner core is solid because it is made of very dense, or heavy, materials - like iron and nickel. Even though it is very hot, these materials don't melt very easily, so they stay solid. Answer 3: It turns out that many materials can be a solid at a higher temperature if the pressure is also higher.

In which layer can air temperatures reach 1,800 degrees celsius?

Air temperatures can reach 1,800 degrees Celsius in the Thermosphere layer of the Earth's atmosphere, which is located above the Mesosphere. The Thermosphere is the layer where solar radiation is absorbed, causing temperatures to rise significantly due to the low density of air molecules.

The difference in air temperature over land compared to over water causes convection currents in the atmosphere. How would a person at the beach experience these convection currents?

A person at the beach might feel cooler air coming from the ocean during the day as the warmer air over the land rises and draws in the cooler ocean breeze. At night, the opposite may occur, with warmer air moving from the land towards the cooler ocean. This circulation of air due to temperature differences is what creates convection currents in the atmosphere.

What is -30 degrees celsius in farenheit?

-30 degrees on the Kelvin scale doesn't exist.

-30 degrees Centigrade on the kelvin scale is

-30+273.15=243K
