Four students are carrying out different laboratory procedures. Piroja is mixing baking soda and vinegar to see if it reacts.
Jason is heating salt water over a burner until the water evaporates.
Kali is putting crushed ice and ice cubes on a table to see which melts first.
Francisco is separating iron filings from sand using a magnet.
Which experiment relies on convection?
Piroja’s experiment
Jason’s experiment
Kali’s experiment
Francisco’s experiment

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.
