Earth's gravitational potential energy: GPE = mgh = Gravity (9.81m/s2) Mass (kg) x Height (m)
Kinetic energy: KE 1 / m2
How would you calculate the gravitational potential energy of a 2 kg bottle of
soda falling off of a kitchen table that is 0.76 m tall?

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?

What is one real world example of a colligative property?
