This is about thermal expansion of water So if there are two glasses of water, one of them is +7°c and the other one is -7°c which one of them has more volume?
Options
a) +7°c
b) -7°c
c) both of them are the same
d) it’s impossible to know

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
