Abox of mass 3kg is lifted onto a shelf. calculate the change on its gravitational potential energy. the gravitational field strength is 10n/kg.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Ethanol has a heat of vaporization of 38.56 kj/mol and a normal boiling point of 78.4 c. what is the vapor pressure of ethanol at 14 c?

Global climatic patterns are changing because of the melting of polar ice caps. the melting of polar ice caps is an example of the interaction between the atmosphere and cryosphere cryosphere and geosphere hydrosphere and geosphere biosphere and cryosphere
