When a system does work and no heat is added to the system its temperature?
remains constant From Rafaelrz. When a simple closed system does work and no heat is added, the temperature of the system will drop. This is because the work is done at the expense of his internal energy, which is thermal energy.
What is the relationship between heat added to a system and the internal energy and external work done by the system-?
When heat is added to or is absorbed by a system, its internal energy increases. The amount of external work a system can do essentially refers to the amount of energy it can transfer to something else. So when internal energy increases, so does the external work done by the system.
Is temperature a work done?
No, HEAT is work done!
It isn't possible to transfer heat from an object at a lower temperature to another object at a higher temperature unless?
It isn't possible to transfer heat from an object at a lower temperature to another object at higher temperature unless work is done to the system. An example of this is a refrigerator.
Is the work-done in isothermal system is zero why?
If a reaction is carried out in constant temperature and constant volume no work is done and heat exchanged with surroundings is equal to the internal energy.

What happens when heat is added to a system?
When heat is added to a system, the temperature increases, unless there is a phase change taking place. In that case, temperature remains the same, and the only observable difference is the phase change.

When heat is added to or is absorbed by a system, its internal energy increases. The amount of external work a system can do essentially refers to the amount of energy it can transfer to something else. So when internal energy increases, so does the external work done by the system.
If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant?
Heat of reaction.
If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant there will be no affect on the?
Heat of reaction.
Is temperature a work done?
No, HEAT is work done!
Why do adiabatic temperature changes occur?
In adiabatic process heat is neither added nor removed from the system. So the work done by the system (expansion) in adiabatic process will result in decrease of internal energy of that system (From I st law). As internal energy is directly proportional to the change in temperature there will be temperature drop in an adiabatic process.
What state will most likely result if heat is added to a liquid?
It will change into a gas.Adding heat to or removing heat from a system may result in a temperature change and possibly a change of state. A liquid substance needs heat added to it in order to enter a gaseous state. If enough heat is added to a liquid substance it will change into a gas.
How is heating related to a substance's temperature?
As an object is heated, the rate of increase in temperature is proportional to the rate of heat added. The proportionality is called the heat capacity. Because the heat capacity is actually a function of temperature in real materials, the total amount of energy added will be equal to the integral of the heat capacity function over the interval from the initial temperature to the final temperature. If you just assume an average heat capacity over the temperature range, then the rise in temperature will be exactly proportional to the amount of heat added.

The addition of heat energy to a system always causes the temperature of that system to increase.?
Yes. Adding heat will increase temperature.
