What do you know about Charles' Law? Check all the statements that are true.

1. For a fixed mass of gas, at a constant pressure, the volume (V) is directly proportional to the absolute temperature (T).

2.Using the example of the sealed cylinder above, the volume of gas at the start is recorded as 30 cm3 with a temperature of 30°C. The cylinder is heated further till the thermometer records 60°C. The new volume of the gas is 32.97 cm3.

3.Heat energy is applied to a cylinder containing a specific volume of gas. The temperature of the gas increases. The average velocity of the gas particles increases resulting in an increase in the rate of collisions and the average force per collision. This produces a decrease in pressure inside the cylinder

4.According to the ideal gas law, increasing the volume of a closed reaction container decreases the thermal energy because the pressure and collision frequency decrease.

5.There is no relationship between temperature and volume for gases.
