Answer:
In most materials, as heat energy is absorbed, the density decreases. IF a certain object is heated, it might appear bigger than usual because it expands as the molecules inside moves faster than usual. However the mass of it stays the same while the density decreases.
Explanation:
I think its a option pascal's principal
Here mass is floating on the piston at equilibrium
So it will have constant pressure always remains constant
So final pressure is same as initial pressure = 900 kPa
now we can say
so final pressure is 900 kPa and final volume is 1.14 m^3
The first step in problem solving is of
course, identifying the problem. How could you solve the problem if there is no
problem in the first place? When one gets to identify the problem, the next
step is gathering of information to know more about the problem. One needs to
get to know and examine the pros – the benefits – and con – the flaws – of the
problem well. After doing all the needed data gathering and possibly,
experimentation, when can start looking for the possible solutions of the
problem.
