Robert hooke was a famous scientist who experimented with springs (metal coils). he found that the farther you stretched the spring, the larger the force with which the spring pulled back on you. what was the dependent variable in hooke's experiment?
a. the material the spring was made of
b. the force of the spring pulling on you
c. the distance the spring was stretched
d. the number of coils of metal in the spring

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?
