If gas is cooled from 323 .0 K to 273.15 K and the volume is kept constant what final pressure would result if the original pressure was 750 mmHg?

Identify the electromagnets with poles that are reversed from the electromagnet shown above

The biosphere of the earth is made up of what compound? organic or inorganic?

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)]
