What is an elliptical orbit?

Back

An elliptical orbit is the path that a celestial body takes around another body, shaped like an elongated circle (ellipse). The distance between the two bodies changes as they move along this path.

Front

Which planet has the most elliptical orbit?

Back

Planet C has the most elliptical orbit according to the provided data.

Front

What factors determine the total thermal energy in an object?

Back

The total thermal energy in an object depends on its temperature and mass.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials, where faster-moving particles transfer energy to slower-moving particles.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, which can occur in a vacuum, such as heat from the sun reaching the Earth.

Front

How does gravity affect a planet's orbit?

Back

Gravity from the Sun pulls planets towards it, causing them to speed up when they are closer and slow down when they are farther away.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in an object, which is related to its temperature.

Front

What is the relationship between mass and thermal energy?

Back

The total thermal energy of an object increases with its mass, assuming the temperature remains constant.
