The measure of thermal energy in an object is temperature.
The measure of thermal energy in an object is called temperature. To determine the temperature of an object, you can use a thermometer. The thermometer works by measuring the expansion or contraction of a substance, such as mercury or alcohol, due to changes in temperature. By observing the level at which the substance rises or falls in the thermometer, you can determine the temperature of the object. Therefore, the correct answer is temperature.
