Question

Pressure vs. Temperature

a) Pressure and temperature are directly proportional. As pressure increases, temperature also increases, provided the gas law variables are held constant.
b) Volume and the amount of gas.
c) Heating a fixed amount of gas in a closed container increases both pressure and temperature.
d) none of above

Answer 1

When volume is constant, pressure is directly proportional to temperature. When pressure is constant, volume is directly proportional to temperature.

Step-by-step explanation:

When volume is constant, pressure is directly proportional to temperature. When pressure is constant, volume is directly proportional to temperature. These relationships are known as Amontons's law and Charles's law respectively. For example, if the temperature on the Kelvin scale increases by a certain factor, the gas pressure also increases by the same factor.
