You drop an ice cube into a glass of warm water. Compared to the
molecules in the water, the molecules in the ice*
O
Have a lower average kinetic energy
O
Have a higher average kinetic energy
Have the same average kinetic energy
O
Have no kinetic energy

When a neutral charge, comes into contact with a positive charge they repel each other nothing happens the neutral charge becomes negative they attract each other

What is meant by the statement" the melting poin of glycerine is 13 degree celsius

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
