Q1) If the amount of heat needed for 3kg of a material for a phase change is 300kJ, calculate the specific latent heat of 5 kg of that material. Show the work out. Q2) A metal block of mass 500g is heated from 30⁰C to 230⁰C, an electric heater was used for 2 minutes to raise the temperature of the block. The specific heat capacity of the metal is 0.5J/g⁰C. Find the power rating of the heater.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
