What is specific heat capacity?
Amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius
The amount of light required to raise the temperature of a substance
The amount of electricity required to raise the temperature of a substance
The amount of pressure required to raise the temperature of a substance
How is specific heat capacity different from heat capacity?
Specific heat capacity is measured in joules, while heat capacity is measured in calories.
Specific heat capacity is used for solids only, while heat capacity is used for liquids and gases.
Specific heat capacity measures heat required to raise the temperature of a unit mass, while heat capacity measures heat required to raise the temperature of a substance.
Specific heat capacity measures the amount of heat released by a substance, while heat capacity measures the amount of heat absorbed by a substance.
What are the units of specific heat capacity?
N/m^2
J/kg°C
m/s^2
Kg/m^3
What is radiation in the context of heat transfer?
Transfer of heat through electromagnetic waves
Transfer of heat through convection
Transfer of heat through conduction
Transfer of heat through sound waves
How does heat transfer occur in solids?
Convection
Absorption
Conduction
Reflection
What are the factors that affect the rate of heat transfer?
Humidity, air pressure, wind speed
Time of day, altitude, distance from the equator
Temperature difference, surface area, material type, and thickness of the material
Color of the material, weight of the material, shape of the material
Explain the concept of thermal equilibrium.
Two or more objects reach the same temperature and there is no net flow of heat between them.
Thermal equilibrium is when objects of different materials reach the same temperature and there is a continuous flow of heat between them.
Thermal equilibrium occurs when one object is hotter than the other and heat flows from the hotter object to the cooler one.
Two objects reach different temperatures and there is no net flow of heat between them.
How is heat related to temperature?
Heat is the same as temperature
Heat has no relationship to temperature
Heat is the measure of the average kinetic energy of the particles in a substance
Heat is the energy transferred between substances due to a difference in temperature.
Heat is a form of
(a)
