Question:

Part A If the specific heat of methanol is 2.51 J/K-g, how many joules are necessary to raise the temperature of 12 g of meth
Part A If the specific heat of methanol is 2.51 J/K-g, how many joules are necessary to raise the temperature of 12 g of methanol from 26°C to 78°C ? IVO AJ o B ? Submit Request Answer

Answers

Given:

m = 12 g

C = 2.51 J/g.K = 2.51 J/g.oC

Ti = 26 oC

Tf = 78 oC

use:

Q = m*C*(Tf-Ti)

Q = 12*2.51*(78-26)

Q = 1.6*10^3 J

Answer: 1.6*10^3 J
