A system had 150 kj of work done on it and its internal energy increased by 60 kj. How much energy did the system gain or lose a
mina [271]

Answer:

The system loses 90 kJ of heat

Explanation:

We can answer the question by using the 1st law of thermodynamics, which states that:

\Delta U=Q-W

where

\Delta U is the change in internal energy of the system

Q is the heat absorbed by the system (positive if absorbed, negative if released by the system)

W is the work done by the system (positive if done by the system, negative if done by the surrounding on the system)

In this problem, we have:

W=-150 kJ is the work done (negative, because it is done by the surrounding on the system)

\Delta U=+60 kJ is the increase in internal energy

Using the equation above, we can find Q, the heat absorbed/released by the system:

Q=\Delta U+W=+60 kJ+(-150 kJ)=-90 kJ

And the negative sign means that the system has lost this heat.

How does the size of a planet affected the amount and type of gas in its atmosphere
dalvyx [7]
There are lots of variables that directly and indirectly contribute to the presence of gas on a surface
if the size of a planet is relatively small it will in turn be that of a smaller area which results in the less area to be covered for gas which basically means higher presence
I can go in depth more but I don't think that would be necessary all you need to know is this ...based on the size and gas will in turn be parallel to it's conformity
