3. how much energy in joules is required to evaporate .0005 kg of liquid ammonia to vapor at the same temperature? 4. how much energy ( in megajoules ) is given up by .75 kg of water at 0c when it freezes to form ice at 0c? 5. explain how heat works between and at critical temperatures?

Generally, for solids dissolving in liquids, a decrease in temperature

What is an effect of gravity on objects on the surface of earth? check all that apply. objects “fall” toward the center of earth. objects are pulled by earth but do not pull on earth. objects accelerate at a rate of 9.8 m/s each second. objects travel at a rate of 9.8 m/s toward the center of earth. objects are pulled by earth more strongly than they pull on earth.
