A gas was compressed and its final temperature, pressure, and volume were 20k,50Kpa, and 10m3 respectively. If the initial volume and pressure were 20m3 and 25Kpa respectively calculate the initial temperature of the gas

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
