) The temperature of a sample of water changes from 10 and degC to 20 and degC when the water absorbs 100 calories of heat. What is the mass of the sample?
one calorie of heat is able to raise one gram of water one degree Celsius so 400 calories could raise 1g of water 400 degrees, so it would raise the 80g by(400/80) 5 degrees Celsius plus the initial temp of 10 degrees, the 80g of water would have a final temp of 15 degrees Celsius

The specific heat of lead is 750kg degrees Celsius How much heat is needed to raise the temperature of a 500kg sample of lead by 50 degrees Celsius?
Multiplying: (spec.heat J.kg-1.K-1)*(masskg)*(temp.difference K or oC)= Heat needed (J)128 (J.kg-1.K-1) * 500 (kg) * 50 (K) = 3.2*106 J = 3200 kJSpecial Notes:J is Joule, SI unit for energy !!Temp. difference in Kelvin (K) = same in degree Celsius (oC)Spec. heat of Lead is 128 (J.kg-1.oC-1), not 750 !!but of Potassium 750 (J.kg-1.oC-1)

How can water made to boil at 95 degrees celsius or 105 degrees celsius?
it can be made to boil at 105 degrees Celsius if we add impurities to it,as impurities raise the boiling point.

How many calories are needed to heat up 5 grams of water by 3 degrees Celsius?
(5)(3)= 15 calories. 1 calorie is the energy (heat) to raise 1 gram of water by 1 degree celsius, so 5 grams of water (3 degrees Celsius) = 15.
