Suppose you want to heat 40 g of water by 20 degrees celsius how many joules of heat are required?
The heat required will be equal to 87.8 kJ.Energy = Specific heat capacity x mass x change in TemperatureQ = Cg x m x change T= 4.18 x 300 x 70= 87780 J= 87.8 kJDensity of water is 1.00 g / cm3Heat capacity of water = 4.18 J oC-1g-1
How many joules of heat are required to heat 20.5g of tin from 30degrees c to 230 degrees c?
q = (20.5 g)(0.21 J/gC)(230o C- 30o C) = 861 Joules =========
Suppose you want to heat 40g of water by 20c how many joules of heat are required?
334.8 Joules
How much heat is required to raise the temp of 106g of aluminum from 96 degree celsius to 121 degree celsius?
Specific heat of aluminum is 0.902 J/gC Use this formula. q(Joules) = mass * specific heat * change in temperature q = 106 grams Al * 0.902 J/gC *(121 C = 96 C) = 2390 Joules of heat
How many joules of heat are required to heat 69 g of lead from 25.5 degree Celsius to 85.6 degree Celsius?
539 joules, approx.
How many joules are required to boil 21.1 g of water at 100 C?
The needed heat is 47,65 Joules.
How many kilocalories are required to melt 16g of ice?
This heat is 32,48 joules.
How many joules of energy are required to raise the temperature of 20g of aluminum from 10 degrees C to 15 degrees C?
Heat energy Q = mass x specific heat capacity x temperature change. Q = m*c*delta T Q = Joules m = kg c (aluminum) = 895.8 J/kg delta T = degr.C temp. change Answer: Q = (20/1000) x 895.8 x 5 = 89.58 Joules (Specific heat capacity of aluminum is obtained by multiplying its specific heat of 0.214 with c of water which is 4186 J/kg = 0.214 x 4186 = 895.8 J/kg).
How many kilojoules of heat must be transferred to a 480 g aluminum pizza pan to raise its temperature from 23 degree c to 234 degree c?
0.902 J/gC is the specific heat of aluminum. Use (q)heat(Joules) = mass * specific heat * change in temperature q = (480 g)(0.902 J/gC)(243 C - 23 C) = 95261.2 Joules ------------------------------( call it 9.5 X 104 Joules )

An aluminum cooking surface heats up uniformly from 250K to 450K The mass of the surface is 3.5 kg and the specific heat of aluminum is 897 J kg K How much heat is required for this process?
The energy in Joules required to cause the 200 K increase in the temperature of 3.5 kg of Aluminium (with a specific heat capacity or SHC of 897 J kg K) equals:Energy (J) = Change in Temp (K) x mass (kg) x SHC (J kg K)Energy (J) = 200 x 3.5 x 897= 627,900 Joules.
