Question

An unknown mass of each of the following substances, initially at 23.0, absorbs 1910 of heat. The final temperature is recorded as indicated. Find the mass of the substance, given: Pyrex glass (55.5)

Answer 1

The data not given here is the specific heat capacity of pyrex glass equal to 0.75(J/g  °C). In this case, heat is equal to mass x specific heat capacity x temperature rise. Temperature difference is then equal to 1910 J / 0.75 J/g  °C / 23 g equal to 110. 75  °C
