1.the pressure of a balloon begins at 2.45 atm and a volume 2.00 L. If the balloon's pressure increases to 3.60 atm then what does the volume change to? 2.The volume of a balloon begins at 1.00 L and the temperature is 25 degrees C. What is the new temperature if the volume changes to 4.00 L?

How many atoms of oxygen are contained in 160 grams of n2o3

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)]

Water undergoes a large change in density at 0 ∘ c as it freezes to form ice. calculate the percent change in density that occurs when liquid water freezes to ice at 0 ∘ c given that
