Question

complete the following statements about temperature and energy.

• temperature is a measure of the type your answer... kinetic energy of the particles in a sample of matter
• the si unit of heat and all other forms of energy is the type your answer...
• heat is he energy transferred between samples of matter because of a difference in their type your answer...
• the type your answer... of a substance is the amount of energy required to raise the temperature of one gram by one celsius degree (1°c) or one kelvin (1 k).

Explanation:

1. Temperature measures the average kinetic energy of particles in a matter sample.
2. The SI unit for all energy forms (including heat) is the joule (J).
3. Heat transfer occurs due to a temperature difference between matter samples.
4. Specific heat capacity is the energy needed to raise 1 gram of a substance by 1°C (or 1 K).

Answer:

• Temperature is a measure of the $\boldsymbol{\text{average}}$ kinetic energy of the particles in a sample of matter.
• The SI unit of heat and ALL other forms of energy is the $\boldsymbol{\text{joule (J)}}$.
• Heat is the energy transferred between samples of matter because of a difference in their $\boldsymbol{\text{temperatures}}$.
• The $\boldsymbol{\text{specific heat capacity}}$ of a substance is the amount of energy required to raise the temperature of one gram by one Celsius degree ($1^\circ\text{C}$) or one kelvin ($1\text{ K}$).
