Discuss how gravity impacts how galaxies behave when they get close to one another

Gravity can have the ability to pull on the matter of another galaxy and can tear apart systems, change the course of movement of parts within each galaxy and change the direction of the galaxy as a whole. We galaxies crash into one another, they will tear each other apart, wreaking havoc, and eventually creating a new galaxy system. 

1184 kJ/kg

Explanation:

Given:

water pressure P= 28 bar

internal energy U= 988 kJ/kg

specific volume of water v= 0.121×10^-2 m^3/kg

Now from steam table at 28 bar pressure we can write

therefore at saturated liquid we have specific enthalpy at 55 bar pressure.

that the specific enthalpy h =  h at 50 bar +(55-50)/(60-50)*( h at 50 bar - h at 60 bar)

h= 1184 kJ/kg
