A 30.0 L sample of nitrogen inside a rigid, metal container at 20.0˚C is placed inside an oven whose temperature is 50.0 ˚C. The pressure inside the container at 20.0˚C was at
3.00 atm. What is the pressure of the nitrogen after its temperature is increased?

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
