If the temperature of a planet is to remain constabt the energy in must equal the energy out?
Yes, for a planet's temperature to remain constant, the energy it receives from external sources, such as sunlight, must equal the energy it emits back into space, typically in the form of infrared radiation. This balance is known as radiative equilibrium. If the energy input exceeds the energy output, the planet will warm, while if the output exceeds the input, it will cool. This principle is fundamental to understanding climate dynamics and planetary atmospheres.

How does accretion heat a planet?
During accretion, any object falling towards a planet will acquire a velocity because of the gravitational attraction from the planet. So, the object will have a kinetic energy due to its motion. During the the collision the kinetic energy is converted to heat energy, and the remain of this heat is actually heating the planet.
What happens to the thermal energy of a substance during a physical change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
Why does the temperature remain same during melting when all ice changes into water?
The temperature remains the same during melting because all the heat energy is used to break the bonds holding the ice molecules together, rather than increasing the temperature. This energy is known as the latent heat of fusion. Once all the ice has transformed into water, the temperature can then increase as more heat energy is used to raise the temperature of the liquid water.
When gas allowed to expand what will be its effect on its temperature?
When gas expands, its temperature typically decreases if the process occurs without the addition of heat (an adiabatic process). This is because the gas does work on its surroundings as it expands, which requires energy, leading to a reduction in the internal energy and, consequently, a drop in temperature. However, if heat is added during the expansion, the temperature may remain constant or even increase.
What happens when different amount of water at different temperature together?
When water of different temperatures is mixed, the final temperature will be a weighted average of the initial temperatures, based on the amounts of each. Energy will transfer from the hotter water to the colder water until thermal equilibrium is reached. The total energy in the system will remain the same, but will be distributed among the water molecules based on their new, final temperature.

What the free energy will be if the temperature is kept uniform in a system?
If the temperature is kept uniform in a system, the free energy will remain constant. Free energy, also known as Gibbs free energy, depends on temperature and is a measure of the system's ability to do work. When the temperature is held constant, there is no change in the free energy of the system.
Why does the temperature remain constant in the highlighted portion of the graph even thermal energy is being added?
the extra energy goes into breaking the bonds in the solid
When adding energy in the form of heat the temperature?
The temperature may increase. It may also remain unchanged; in which case the energy is used to change the state of matter (for example, melting a solid, converting it to a liquid).
How can the temp of a substance remain the same if it is absorbing energy?
The temperature of a substance can remain the same while absorbing energy if it is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed energy is used to break intermolecular bonds rather than increase the kinetic energy of the particles, which keeps the temperature constant.
What happens to the temperature of boiling water when heat is added to the boiling water?
If you add energy to a boiling liquid, it will just boil faster, but the temperature will remain the same, at the boiling point. All the energy goes into phase change, not heating.
How can the temperature of a substance remain the same even if the substance is absorbing thermal enerrgy?
The temperature of a substance can remain the same during absorbing thermal energy if the substance is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed thermal energy goes into breaking intermolecular bonds rather than increasing the temperature. Once the phase change is complete, the temperature will resume rising as the substance absorbs more thermal energy.
How can the temperature of substance remain the same even if the substance is absorbing thermal energy.?
For example, when ice is melting, the absorbed thermal energy is used to change the phase of the substance - a type of potential energy.
What happens to temperature when energy is added as heat?
When energy is added as heat, the temperature of a system increases because the particles in the system gain kinetic energy and move faster. This increase in temperature is a result of the particles vibrating or moving more rapidly, leading to a rise in the average kinetic energy of the system.
Why does the temperature of any substance remain constant during the change of a state?
because energy is required to break the intermolecular forces in the molecule
How can the temperature of a substance remain the same even if the substanceis absorbing thermal energy?
That happens, for example, when ice melts. In this case, energy is spent to break the bonds between the water molecules. In other words, the kinetic energy (movement) of the water molecules doesn't increase, but its potential energy does.
What happens to temperature as energy is added to a substance that is changing state?
The temperature remains constant during a change of state as the energy is used to break intermolecular bonds rather than increase molecular motion. Once the substance has completely changed state, the temperature will start to rise again as the added energy increases the molecular motion.
