Agas has experienced a small increase in volume but has maintained the same pressure and number of moles. according to the ideal gas law, how has the temperature of the gas changed? it has increased two times. it has increased slightly. it has decreased slightly. it has stayed the same. mark this and return save and exit

 It has increased slightly.

Explanation: As the pressure and moles are constant, an increase in volume would lead to an increase in temperature according to Boyle's law.

According to ideal gas law:

 (for same no of moles)

As pressure is also constant,

thus equation is reduced to

or

Which says Volume is directly proportional to temperature, thus increase in volume will lead to increase in temperature.

 The correct answer is :'It has increased slightly.'

Explanation:

As the pressure and moles are constant, an increase in volume would lead to an increase in temperature according to Charles's law.

The law states that ; at constant pressure and moles of gas ,the volume occupied by an ideal gas is directly proportional to the temperature of the gas in Kelvins.

(at constant pressure and moles of gases)

According to ideal gas law:  

 (for same no of moles)

As pressure is also constant,

Hence, the equation is reduced to

So, when the with slight increase in the volume of the gas slight increase in temperature of the gas will be observed.
