A40.0-g block of ice at -15.00°c is dropped into a calorimeter (of negligible heat capacity) containing water at 15.00°c.

when equilibrium is reached, the final temperature is 8.00°c.

how much water did the calorimeter contain initially?

the specific heat of ice is 2090 j/kg • k, that of water is 4186 j/kg • k, and the latent heat of fusion of water is 33.5 × 104 j/kg.

Explanation:

Given:

Now, assuming that there is no heat loss out of the mixture:

⇒ heat absorbed by the ice = heat rejected by the water

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
