Asteel container of mass 160 g contains 23.0 g of ammonia, nh3, which has a molar mass of 17.0 g/mol. the container and gas are in equilibrium at 16.0°c. how much heat (in j) has to be removed to reach a temperature of −20.0°c? ignore the change in volume of the steel. (the specific heat of steel is 452 j/(kg · °c). enter the magnitude.)

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
