you need the specific heat of aluminium
c = .9 J/(Kg*K)
140 +273 = 413 K
73 +273 = 346 K
413-346 = 67 k
c*T*m = .9 (J/(Kg*K) * 67 K * 48 Kg = 2894.4 J
46 calories (or 192, 464 joules) for each Celsius degree.
specific heat(; your welcome!
0.131 joules/gram'C x 1.3 grams x (46-25)'C = 3.5763 joules
If all 1700 Joules of work get converted into heat, then, of course, you get 1700 Joules of heat.
Specific heat is the heat energy in joules required to rise the temperature of one kg of substance through one kelvin without a change in its state. But latent heat is the heat required to change the state of one kg of substance without change in temperature.
How much heat (in calories) is required to heat a 43 g sample of aluminum from 72 F to 145F
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 =============
334.8 Joules
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
419.1 Joules are required to heat one gram of liquid water from 0.01 degC to 100 deg C. So the answer is 419.1*46 = 19278.6
539 joules, approx.
The needed heat is 47,65 Joules.
I will use this formula, the convert. q( in Joules ) = mass * specific heat Au * change in temp. q = nCT q = (150 grams)(0.129 J/gC)(175 C - 25 C) = 2902.5 Joules Now, 1 calorie = 4.184 Joules 2902.5 Joules (1 calorie/4.184 Joules) 694 calories required
46 calories (or 192, 464 joules) for each Celsius degree.
46 calories (or 192, 464 joules) for each Celsius degree.
This heat is 32,48 joules.
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).
