A 300 gram lead ball with a temperature of 80°C is placed in 300 grams of water at a temperature of 20°C. The specific heat capacity of lead is 16 J/gºC and the specific heat
capacity of water is 4.18 J/gºC. When the system reaches equilibrium what is the equilibrium
temperature?

ill do it for 100, also this isnt 80 its 40

the bal will not change its velocity.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
