You have 53 g of aluminum at25 degrees C.
How much heat must be added to raise its
temperature to 139 degrees C? Assume the specific
heat of aluminum is 903 J/kg · degrees C.
Answer in units of J
q=m*c*change of t
m=mass
c= specific heat
change of t= final temp- initial temp
fill in these with your numbers and you should get the answer
is it supposed to be a really high number?
sorry convert your 53 grams to kg. because your specific heat capacity is in J per kg
this should change your answer
right. or change specific heat to 0.903 J/g.
To calculate the amount of heat required to raise the temperature of aluminum, we need to use the formula:
Q = m * c * ΔT
Where:
Q is the heat energy in joules,
m is the mass of the aluminum in kilograms,
c is the specific heat capacity of aluminum in J/kg · degrees C, and
ΔT is the change in temperature in degrees C.
First, we need to convert the given mass of aluminum from grams to kilograms:
m = 53 g / 1000 = 0.053 kg
Next, we can calculate the change in temperature:
ΔT = 139 degrees C - 25 degrees C = 114 degrees C
Now, we can plug in the values into the formula to find the amount of heat required:
Q = 0.053 kg * 903 J/kg · degrees C * 114 degrees C
Calculating this expression will give us the answer in joules.
