WebApr 6, 2024 · 1) If 968 joules of heat is required to raise the temperature of the 50 g of substance from 3000c to 4000c. Then, calculate the specific heat of the substance. Solution: Given, amount of heat required = Q = 960 joules The mass of the substance = m = 50 g The change in temperature = ΔT = T2 - T1 = 40 - 30 = 100C WebOct 30, 2024 · Diatomic gases under ambient conditions generally have a molar specific heat of about 7 c a l m o l − 1 K − 1, and one mole of hydrogen has only 2 g mass. Thus 3.5 c a l g − 1 K − 1 for hydrogen versus 1 c a l g − 1 K − 1 for water. Helium, contrary to the question, is 5 c a l m o l − 1 K − 1, not 7 c a l g − 1 K − 1. Share Improve this answer
