Best Answer

you need to know the specific heat capacity of aluminum first which can be denoted as 'c'.

then using the formula:

H=MC(dt) where 'dt; is the change in temperature, M is the mass and H is energy needed, you can thus calculate H.

i think the value of 'c' for aluminum is around 0.88Jg/K

Replace given values in the equation, you will surely get the answer!

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 )


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 much heat in joules to heat a 40 g sample of aluminum from 73 degrees f to 142 degrees f?

q( in Joules ) = mass * specific heat * change in temperature [ convert temps--Tf = Tc(1.80) + 32 ] q = (40 g)(0.90 J/gC)(61.1o C - 22.8o C) = 1.4 X 103 Joules =============


How much heat is generated by 1700 joules of work?

If all 1700 Joules of work get converted into heat, then, of course, you get 1700 Joules of heat.


What is the total heat loss if you have 18 grams of aluminum and the temperature changes from 64 degrees Celsius to 48 degrees Celsius?

Approx 4974 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).
