Questions and Answers

What is the SI unit of heat?

Calorie (cal)

Kelvin (K)

Watt (W)

Joule (J) (correct)

How is temperature conversion from Celsius to Kelvin represented?

$t(k) = t°C / 273.15$

$t(k) = t°C + 273.15$ (correct)

$t(k) = t°C * 273.15$

$t(k) = t°C - 273.15$

What is the definition of heat?

A measure of hotness or coldness of a body.

The ability to do work or cause a change.

A form of energy flow between two bodies or between a body and its surroundings by virtue of temperature difference. (correct)

Study Notes

Heat and Temperature Concepts

SI unit of heat is the Joule (J), which measures energy transfer due to temperature differences.
Temperature conversion from Celsius to Kelvin is represented by the formula: K = °C + 273.15.
Heat is defined as the energy transferred between systems or objects due to a temperature difference—essentially, heat flows from a hotter object to a colder one.
Ice point, or the freezing point of water, occurs at 0°C, which is equivalent to 273.15 K in the Kelvin scale.
Heat flows from areas of higher temperature to areas of lower temperature, aligning with the second law of thermodynamics.
