Temperature and Average kinetic energy of moleces

In summary, the conversation discusses how the temperature of air will change depending on the speed of a hydrogen molecule being added or removed. This change in temperature will occur if the speed is higher or lower than 1980 m s/-1. However, this assumption may not be accurate as the average speed of all molecules is not specified. The exact change in temperature cannot be determined without knowing this information.

Is the assumption here that the average speed of all the molecules is 1980 m s/-1? Because if it is not, the answers could be anyone's guess.

Also, what do you think the answer should be?

1. What is temperature?

Temperature is a measure of the average kinetic energy of molecules in a substance. It is a measure of how hot or cold a substance is.

2. How does temperature affect the average kinetic energy of molecules?

As the temperature increases, the average kinetic energy of molecules also increases. This is because at higher temperatures, molecules have more energy and move faster.

3. How are temperature and average kinetic energy of molecules related?

The average kinetic energy of molecules is directly proportional to the temperature. This means that as one increases, the other also increases.

4. What is the unit of measurement for temperature and average kinetic energy of molecules?

The unit of measurement for temperature is usually degrees Celsius (°C) or Kelvin (K). The unit for average kinetic energy of molecules is typically joules (J) or electron volts (eV).

5. How is temperature measured?

Temperature can be measured using various instruments such as thermometers, pyrometers, and thermistors. These instruments measure changes in physical properties of substances, such as expansion or electrical resistance, which can then be converted into temperature readings.
