Calculating the amount of ice that needs to be melted before thermal equilibrium occurs.

8 grams of water at 100 degrees C are poured into a cavity at 0 degrees C. How many g of ice melt before thermal equilibrium is attained?

Calculating the resulting temperature of water and aluminum in a calorimeter.

A 0.5kg mass of aluminum at 0 degrees Celsius is put in 1 kg of water at 78 degrees Celsius in a Calorimeter of negligible mass. What is the resulting temperature at equilibrium?

Calculating the final temperature of an ideal gas after the internal energy has been increased.

Heat is added to an ideal gas at 20 degrees C. If the internal energy of the gas increases by a factor of three, what is the final temperature (in degrees C)?

Latent heat fusion with average

Calculate the latent heat fusion of the attached data Lf =_______________inJ/Kg. See attachment below. I have worked on this problem for hours and I haven't come up with the correct answer. Help please!!! I'm unsure if the attachment posted let me know if it didn't.

Calculating the final temperature when ice is added to water.

When 50 g of ice at 0 degrees is added to 50 g of water at 25 degrees Celsius, what is the final temperature in degrees C?

Calculating the final temperature after heat is added to a block.

A 2 kg block of aluminum is originally at 10 degrees C. If 140 kj of heat is added to the block, what is the final temperature in degrees C?

Calculating how much ice melts after hot water is poured over it.

7 kg of water at 90 degrees C is poured into a very large (much more than 7kg) block of ice which is at 0 degrees C. How much (in kg) ice melts?

Calculating the equilibrium temperature of two substances.

A 10kg aluminum block of (c=920J/KgC) at 75 degrees C is dropped into 100kg of water ( c=4186J/kgC) at 50 degrees C. Assuming the heat only passes between the water and the aluminum (no losses) what will the equilibrium temperature (in degrees C) be?
