a gas has an intial volume of 2.75L at a temperature of 285K. if the temperature changes to 380K, what is the new volume of the gas if the pressure is unchanged?
Suppose the gas is ideal gas. According to the ideal gas equation of state, pV = nRT, the pressure is unchanged. So Vi/Ti = nR/p = Vn/Tn. (i stands for initial and n stands for new) So the new volume Vn = 3.67 L
