Answer : The temperature of gas is, 295 K
Explanation :
To calculate the temperature of gas we are using ideal gas equation:
where,
P = Pressure of gas = 1.21 atm
V = Volume of gas = 10.0 L
n = number of moles = 0.500 mole
R = Gas constant =
T = Temperature of gas = ?
Now put all the given values in above equation, we get:

Therefore, the temperature of gas is, 295 K
C. Chemical change because it doesn’t change it chemical makeup but it will change temps it’s physical appearance and phase change or change of state
