Answer:
53676 J
Explanation:
m = 355 g
c = 2.4 J/gºC
ΔT = 63°C
q = mcΔT
= (355)(2.4)(63)
= 53676 J
The amount of heat is 53676J to raise the temperature of 355 g of ethanol.
Temperature is a measurement of the amount of energy of the atoms in a system or a physical quantity that expresses hot and cold.
Heat is energy that is transmitted through one body to some other due to a temperature differential. When two bodies of different temperatures come together, energy can be transferred (heat flows) from the hotter to the colder.
It can be determined by the formula:
q =mCΔT.
where, q is heat, m is mass , C is and T is temperature.
Calculation of heat is shown below:
It is given that, mass of ethanol = 355 g, c = [tex]2.4 J/g^{0}[/tex] C, ΔT. = [tex]63^{0} C[/tex]
Now, put the values of given data in heat formula:
q =mCΔT
= 355×2.4×63
=53676J.
Therefore, the amount of heat will be 53676J to raise the temperature of 355 g of ethanol
