Which is measured using a calorimeter? changes in potential energy changes in kinetic energy changes in thermal energy changes in temperature

changes in thermal energy

Explanation:

A calorimeter is usually filled with water. Then, a hot material is placed in the water: the material transfer heat to the water, which is initially colder, until they have the same temperature (thermal equilibrium). By measuring the change in temperature of the water inside the calorimeter, it is possible to calculate the change in thermal energy (which is equal to the heat released by the material). In fact, the heat absorbed by the water is equal to the heat released by the material:

where

is the mass of the water

is the specific heat of the water

is the temperature change of the water

is the mass of the material

is the specific heat of the material

is the temperature change of the material

By knowing the mass of the water, its specific heat and by measuring the temperature change of the water, one can calculate the change in thermal energy.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
