Louisa found that she could melt 150g of lead at 3275 C. At what temperature could she melt 75g of lead?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

Properties seen when one one substance changes to another are known as properties
