What has more thermal energy? a frozen block of ice or a pot filled with boiling water? and explain, you!

That depends on how you define and measure "thermal energy". The concept is not well-defined or broadly accepted in thermodynamics because the "thermal energy" is typically assumed to refer to internal energy present in a system due to its temperature. Internal energy can be changed without changing the temperature, and there is no way to distinguish which part of the internal energy is "thermal". Instead, the appropriate thermodynamic concept when talking about something "thermal" is HEAT: defined as a transfer of energy due to differences in temperature (just as work is another type of transfer of energy). Heat and work therefore depend on the path of transfer and are not state functions, whereas internal energy is a state function. If we equate "thermal energy" with "internal energy" then we are talking a "state function" which requires that we choose the state that we will measure relative to. Altitude is a good example of a state function. We can define altitude as either the distance between the ground and an airborne item (like an airplane or balloon) or we can define altitude as the distance between sea-level and the height of the item. Depending on what we choose as "zero" we get different values. Internal energy is also dependent on total mass, so it would depend on the size of the iceberg and the size of the pool. If you chose to use 0 K as your reference point and had a very large iceberg and a very small pool, the internal energy (or "thermal energy" if we equate the two terms) of the iceberg would be greater. If you choose room temperature the iceberg will have a NEGATIVE internal energy while any pool of boiling water would have a POSITIVE internal energy (hence "more" energy). If you choose something like ice at 0°F, then the size of the two comes into play because both will be positive.

Ibelieve your answer is b.hope this : )
