Pls help I'll report if you put a useless answer A sealed balloon filled with air has an internal pressure of 1.25 atm and a volume of 2.50 liters. If the temperature remains at a constant 25 C, but the volume is compressed to 1.20 liters what is the new pressure?

What does the symbol (–hfus) indicate in a phase change?

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)]
