Question

A calorimeter directly measures ______ in order to calculate ______. (1 point)

changes in temperature; specific heat
radiation; changes in temperature
radiation; specific heat
specific heat; changes in temperature

Answer 1

A calorimeter directly measures changes in temperature in order to calculate specific heat.
Calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity.

Hope this help

Answer 2

The complete sentence is:

A calorimeter directly measures changes in temperature in order to calculate specific heat.

In fact, the amount of energy acquired/released by a substance is directly proportional to its change in temperature due to the equation

`Q=mC_s \Delta T`

where Q is the amount of energy, m is the mass of the substance, Cs is the specific heat of the substance and
`\Delta T` is the change in temperature. Therefore, by knowing Q, m and by measuring the change in temperature, it is possible to calculate Cs, the specific heat capacity of the substance.
