You can add thermal energy to a substance without increasing its temperature by adding hot water. As the thermal energy of the substance increases, the particles of the substance expands. That is how you can open a bottle by putting it under hot water.
If the substance's temperature doesn't increase, it must be undergoing a phase change - such as when ice melts. In that case, the thermal energy is used up to increase the potential energy of the individual particles.
isothermal expansion, state change, isothermal reversible reactions with thermodynamically favored product.
You cannot because temperature is a measure of the average thermal energy of the particles of the substance.
yes-increase its mass
It is possible to add heat to a substance without changing its temperature. That happens during melting and boiling. However, I cannot think of a case in which the temperature of a substance increases without heat being added to it, either by radiation, conduction or convection.
Yes, if the heat goes into a phase change.For example . . .Heat added to ice at 0° C changes the ice to water at the same temperature.Heat added to water at 100° C changes the water to steam at the same temperature.
Dry heat is the absolute substance temperature without accounting for the modulating effects of water vapor in the substance. Moist heat is the relative substance temperature when accounting for the modulating effects of water vapor.
both the heat of fusion and the heat of vaporization
yes-increase its mass
Thermal energy is simply just another term for temperature. Adding thermal energy to any substance will always create a rise in temperature. The only way it would be possible to add thermal energy to a substance without seeing any net increase in temperature would be if the substance lost an equal amount of thermal energy at the same time.Answer:At the melting point and boiling point any input of thermal energy goes to the change of state rather than the rise in temperature. As a consequence boilling water stays at 100oC until it is all evaporated and melting ice stays at 0oC until the entire mass is melted

That happens when there is a phase transition; for example, when ice melts, it takes energy to convert ice at zero degrees, to water at zero degrees.
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
No, thermal energy is entirely energy added for heat.
no
At the melting point a SOLID turns to a LIQUID. (Increasing temperature). At the same temperature , when a liquid turns to solid it is referred to as FREEZING POINT. NB At the boiling point a LIQUID turns to a GAS. (Increasing temperature). At the same temperature , when a gas turns to liquid it is referred to as CONDENSING POINT. NNB Carbon Dioxide, a gas, moves directly to a solid(dry ice) . This is called the SUBLIMATION POINT.
Yes, if the heat goes into a phase change.For example . . .Heat added to ice at 0° C changes the ice to water at the same temperature.Heat added to water at 100° C changes the water to steam at the same temperature.
As with any other substance, without any outside influence, it will take on the ambient temperature.
At a unique temperature, called the "freezing point", for each pure substance at a constant pressure, a solid form of the substance can change from solid to liquid phase by absorbing heat energy from its environment without raising the temperature of the substance, and, at the same temperature and pressure, a liquid phase of the same substance, can solidify without changing its temperature if it can transfer heat energy to the external environment.
