Which is colder 5 degrees or 3 degrees below zero?
3 degrees below zero is colder, as it is below freezing temperature (0 degrees).
Temperature senses use two types of?
The two types of temperature senses are warm receptors and cold receptors. Warm receptors detect increases in temperature, while cold receptors detect decreases in temperature. Together, they help our bodies maintain a stable internal temperature.
How cold is 20 degrees Fahrenheit?
20 degrees Fahrenheit is quite cold, especially if you are not used to colder temperatures. It is equivalent to about -6.7 degrees Celsius.
Why are Popsicle sticks good insulators?
Popsicle sticks are good insulators because wood is a poor conductor of heat, which means it does not transfer heat easily. The air pockets within the wood also help to reduce heat transfer. Additionally, the thinness of the popsicle stick makes it harder for heat to pass through, making it an effective insulator.
If pressure remains unchanged, the volume of the gas will increase when heated. To calculate the new volume, you can use the formula: V2 = V1 * (T2/T1), where V1 is 128 mL, T1 is 20°C, T2 is 40°C, and V2 is the new volume. Plug in the values and solve for V2.
What is the difference between minus 30degrees and 20 degrees?
The temperature difference between -30 degrees and 20 degrees is 50 degrees. Negative 30 degrees is 50 degrees lower than 20 degrees.
What is the boiling temperature of rubber?
It can not reach a boiling point because it decomposes before it boils.
What happens to water molecules when water is heated from 90 to 110 degrees Celsius?
As water is heated from 90 to 110 degrees Celsius, the water molecules gain kinetic energy and move more rapidly. This increased movement causes the water molecules to break hydrogen bonds and transition from a liquid to a gaseous state, forming water vapor.
80 degrees Fahrenheit is considered warm but not excessively hot. It can be comfortable for many people but may feel warm or even hot to others, depending on their preferences and the humidity level.
When does absolute zero happen for Fahrenheit?
Absolute zero for Fahrenheit is -459.67°F. At this temperature, molecular movement ceases completely.
What is the Kelvin temperature of 25 degree Celsius?
To convert Celsius to Kelvin, add 273. So, the Kelvin temperature of 25 degrees Celsius is 298 Kelvin (25 + 273 = 298).
Is the melting point the same temperature as the freezing point for a substance?

What is the lowest temperature that can be endured by humans?
There's no such thing. It's not just a matter of the temperature, but of the length and degree of exposure.
People can go out skiing all day in temperatures below freezing, but you're unlikely to survive even an hour of being in water at, say, 50 degrees Fahrenheit.
What is 22 degrees centigrade in fahrenheit?
Conversion formula: [°F] = [°C] * 9 / 5 + 32 = 22 * 9 / 5 + 32 = 71.6 °F
What was the lowest temperature in Alaksa ever?
Alaska is very remote, the lowest ever documented is -81 degrees below zero. But think we have only had documents of temperature for Alaska for about 30-60years.
What temperature does steel break down?
The specific temperature at which steel breaks down can vary depending on the type of steel and its composition. Generally, steel begins to soften significantly and lose its strength at temperatures above 800°C (1472°F). At even higher temperatures, typically above 1000°C (1832°F), steel may undergo further degradation and ultimately melt.
Depends on the humidity. Usually it's a medium temperature not hot nor cold.
pH is a logarithmic scale, so a change of 1 in pH means a change of 10 in the quantity. It is also negative, so as pH increases the measured quantity actuallly goes down.
The temperature scales are simply direct scales; all changes mean the same thing and going up means going up.
Which is warmer -7 degrees Celsius or -3.5 degrees Celsius?
Let's think about it in terms of degrees F:
-3.5 degrees C = 25.7 degrees F
-7.0 degrees C = 19.4 degrees F
-3.5 degrees C would be warmer since 25.7 degrees F is warmer than 19.4 degrees F.
What is the ground temperature at 300 feet?
The ground temperature at 300 feet below the surface can vary depending on location and depth, but on average, it tends to be relatively stable and is often unaffected by surface temperature fluctuations. In most regions, the temperature at this depth ranges from 50-60 degrees Fahrenheit.
What is the name of the temperature scale used to measure earths heat?
The temperature scale used to measure Earth's heat is called the Celsius scale.
