How do you use thermodynamics steam tables?
The steam tables have 16 columns as follows: pressure (absolute), temperature, specific volume of vapor, specific volume of liquid, heat of the liquid, heat of vaporization, total heat of the vapor, entropy of the liquid, entropy of vaporization, entropy of the vapor, internal heat of the liquid, internal heat of vaporization, and internal heat of the vapor (occasionally the external heat of the liquid, vaporization and vapor are included) If the temperature and pressure of steam are known then cross referencing the heat or the volume of a known quantity of the steam can be done. the heat content(enthalpy) of the liquid or vapor can be extrapolated from the chart, as can the entropy and internal energy. The enthalpy less the internal energy = the external energy (or the actual energy required to expand the liquid to a vapor) By determining the starting heat content of steam and final or exhaust heat content of steam the efficiency of a steam engine can be determined. Along with these calculations are the determinations of heat losses, steam quality, loss to entropy,...etc. all calculated using various instruments and the steam tables.
Is exothermic adding energy?
The meaning of exothermic is "which loss heat".
When gaseous water condensing to a liquid is the gaseous water absorbing the heat or giving off heat?
The energy level of water vapor is higher than that of liquid water because the energy invested in transforming that water into vapor (enthalpy of evaporation/vaporization) is higher than the energy it takes to melt ice (enthalpy of fusion). So when water vapor condenses, that extra energy that was used to cause the phase change from water to gas is released and absorbed by the object it condensed on.
What is the process which transfers energy to the surroundings as heat in the food chain?
The process that transfers energy to the surroundings as heat in the food chain is primarily cellular respiration, which occurs in living organisms. During respiration, organisms convert stored chemical energy from food into usable energy (ATP), while releasing heat as a byproduct. This energy transformation leads to a loss of energy at each trophic level, as not all energy is converted to biomass; some is dissipated as heat into the environment. Consequently, this heat loss is a crucial factor in the efficiency of energy transfer within the food chain.
Heat loss by direct exchange of energy between molecules is called?
Conduction
What is insensible heat loss?
Also Latent Heat Loss. The heat that is lost through the continuous, unnoticed water loss that occurs with vaporization accounting for 10% of basal heat production. Evaporation accounts for the greatest heat loss when body head increases.. Does not result in temperature increase of surrounding air.

Requires a gain or loss of heat energy?
A temperature change requires as gain or loss of heat energy.
What does heat form into?
Heat energy does not form into anything. The "loss of energy" is actually the energy converted into heat.
What is always lost when energy changes form?
Some energy is always lost in the form of heat due to inefficiencies in the conversion process. This loss is known as thermal energy or heat loss.
When one form of energy is converted to another there is always a loss of this?
When energy is converted from one form to another, there is always a loss of energy in the form of heat. This is due to inefficiencies in the process, such as friction or energy transfer losses. This loss of energy is known as the second law of thermodynamics.
Is condensation a energy loss or gain?
Condensation is typically considered an energy loss because it releases energy as heat when water vapor changes to liquid water. This energy is known as latent heat of condensation.
What does loss of energy by friction end up as?
Heat.
Why is no energy transformation efficient?
Due to the heat loss
What is heat absorption and loss?
Heat absorption is the process by which an object takes in heat energy from its surroundings, increasing its own temperature. Heat loss, on the other hand, is when an object releases heat energy to its surroundings, causing its temperature to decrease. Both processes are important for understanding how thermal energy is transferred between objects.
Is evaporation heat gain or heat loss?
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
