Question

based on what you have learned about the units for measuring thermal energy, complete the following passage.
the unit often used in chemistry and physics to measure energy, such as for work or electrical current, is the
. we can also use this unit, as we did in this lab, for measuring
. this is a property that is
quantified by the energy needed per
of material to raise the temperature by one
. the unit for this measure is therefore
.

Explanation:

• The joule (\(J\)) is a common unit for energy in chemistry and physics.
• Specific heat capacity is a property related to the energy needed to change the temperature of a material.
• It is quantified per unit mass (e.g., kilogram, \(kg\)) and per unit temperature change (e.g., degree Celsius, \(^{\circ}C\)).
• The unit for specific heat capacity is \(J/(kg\cdot^{\circ}C)\) (joules per kilogram per degree Celsius).

Answer:

1. joule (\(J\))
2. specific heat capacity
3. unit mass (e.g., kilogram, \(kg\))
4. degree (e.g., degree Celsius, \(^{\circ}C\))
5. \(J/(kg\cdot^{\circ}C)\) (joules per kilogram per degree Celsius)
