Answer:
we neglect the 190N to answer that Question
Answer:
-140
Explanation:
A gas loses 80joules of heat.
The gas also does 60 joules of work
Therefore the change in internal energy can be calculated as follows
= -80 + (-60)
= -80-60
= -140
Hence the change in internal energy is -140
Potable water is also known as drinking water which is safe to drink and for cooking purposes
