A 15.0 L tank of gas contained at a high pressure of 8.20 • 10^4 torr. The tank is opened and the gas expands into an empty chamber with a volume of 600•10^4 L. Calculate the new pressure of the gas

6. what does the symbol ah stand for? o one calorie given off by a reaction the specific heat of a substance the heat capacity of a substance the heat of reaction for a chemical reaction

One does not belong why? ice, gold ,wood ,diamond and table salt

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)]
