I need help on step by step procedures on these types of problems.

I dont even know what this is asking for:
A gas occupies a volume of 500. mL at a pressure of 4 atm. if the pressure is increased to 6 atm and the temperature remains constant what will be the volume of the gas?

Finding Joules:
How many joules does it take to melt 35g of ice at 0 degrees C


Finding final temperature:
What is the final temperature when 2.0L of water at 50 degrees C is poured into a bucket containing 3.0L of water at 25 degrees C.
