A 4 kg. block of copper is removed from a freezer where its temperature was maintained at -23 Co . How much heat does the copper absorb as it is warmed to -3.1 Co ? (The specific heat capacity of copper is 390fraction numerator J over denominator k g space C to the power of ring operator end fraction)

On a cold day, when the air temperature is 0°c, you empty your lungs and take a deep breath, filling your lungs with 4.2 l of air. if you hold your breath until the temperature of the air in your lungs reaches 37°c, what is the volume of the air in your lungs at that point, assuming the pressure does not change?
