The RMS speed of oxygen molecules at 27°C (300 K) is 500 m/s. If the temperature is increased to 927°C (1200 K) at constant pressure, the new RMS speed is:
An ideal gas at constant pressure is heated from 300 K to 600 K. If the initial volume is V, the final volume is:
A gas at pressure P and volume V is compressed adiabatically to V/2. If γ = 1.5, the final pressure is:
A black body at temperature T has peak emission wavelength λ_max. If the temperature is increased to 2T, the new peak wavelength is:
A body cools from 80 degC to 50 degC in 5 minutes in a room at constant temperature 20 degC. Using Newton's law of cooling, the time taken to cool from 60 degC to 30 degC in the same room is approximately:
A Carnot engine has an efficiency of 40% when the sink temperature is 300 K. The source temperature is:
A gas mixture contains 1 mole of a monoatomic gas (C_v = 3R/2) and 1 mole of a diatomic gas (C_v = 5R/2) at temperatures T_1 and T_2 respectively. They are mixed adiabatically in a rigid container. The final equilibrium temperature is:
An ideal gas undergoes an isothermal expansion at 300 K from volume V to 10V. The work done by the gas is: (R = universal gas constant)
