How does the speed of sound in a gas change when you raise the temperature from 0°C to 20°C? Explain briefly.
Calculate the temperature rise of a gas.
(a) You have a bottle containing a mole of a monatomic gas such as helium or neon. You warm up this monatomic gas
with an electrical heater, which inputs Q = 580 joules of energy. How much does the temperature of the gas
increase?
(b) You have a bottle containing a mole of a diatomic gas such as nitrogen (N2) or oxygen (O2). The initial temperature
is in the range where many rotational energy levels are excited but essentially no vibrational energy levels are
excited. You warm up this diatomic gas with an electrical heater, which inputs Q = 580 joules of energy. How much
does the temperature of the gas increase?
(c) You have a bottle containing a mole of a diatomic gas such as nitrogen (N2) or oxygen (O2). The initial temperature
is in the range where not only many rotational energy levels are excited but also many vibrational energy levels are
excited. You warm up this diatomic gas with an electrical heater, which inputs Q = 580 joules of energy. How much
does the temperature of the gas increase?
