How much heat will be required to change the temperature of 10 grams of water from 20^(@)C to 50^(@)C? , 11 | liquid...

The quantity of heat required to raise the temperature of 2000 g of water from 10^@C to 50^@C is

Heat required to raise the temperature of one gram of water through 1^@C is

Heat required to increases the temperature of 1kg water by 20^(@)C

How much heat (in joule) is required to raise the temperature of 205 g of water from 21.2^(@)C to 91.4^(@)C . Specific heate of water is 4.18 J g^(-1) .^(@)C^(-1) Strategy : The specific heat of a substance is the amount of heat required to raise the temperature of 1g of the substance by 1^(@C . Thus Specific heat = (("Amount of heat in joules"))/(("Mass of substance in grams")("Temperature change in" .^(@)C)) Rearrangement gives. Amount of heat (q) = Mass of substance (m) xx Specific heat (c ) xx Temperature change (Delta T)

An electric heater has coil resistance of 12 Omega and is operated from 220 V power line. If no heat escapes from it then how much time is required to raise the temperature of 40 kg of water from 10^(@)C to 80^(@)C ?

How much heat energy is necessary to raise the temperature of 5 kg of water from 20 ^@ C " to " 100^@C ?
