The latent heat of fusion of mercury is 11.8 i/g. the amount of energy , rounded to the nearest tenth needed to change 8.00 grams of mercury to a liquid is ?

Does anyone know how to solve this problem? i really need . i made an attempt but i just cant get it. a metal rod is 25.000 cm long at 25.0 degrees celsius. when heated to 102.0 degrees celsius, it is 25.054 cm long. what is the coefficient of linear expansion for this metal.

Which best describes the difference between internal and thermal energy?

At what time would the magnitude of the velocity reach 36.00 km/hr
