EMERGENCY! TRUE OR FALSE? WORK AND HEAT?

IF WORK IS GREATER THAN ZERO AND


HEAT IS LESS THAN ZERO then the internal energy may, but is not guaranteed to increase. True or false?EMERGENCY! TRUE OR FALSE? WORK AND HEAT?
This is true.





Work is positive; that is it flows into the system.


Heat flow is negative; that is it flows out of the system.





So the internal energy will increase if (using absolute values) the work is greater than the heat flow but will decrease if the heat flow is greater.EMERGENCY! TRUE OR FALSE? WORK AND HEAT?
false verify with newtons law
