Question #84e43

Answer 1

`8.91X10^4J`

Explanation:

The calculation for Joules can be determined using the equation
`Q=m(t_f-t_i)C_p`

`Q =` heat in Joules `(J)`
`m =` mass in (g)
`T_f =` Final Temp `(C)`
`T_i =` Initial Temp `(C)`
`C_p=` Specific Heat of Water `(J/(gC))`

`Q =?`
`m =576g`
`T_f = 58^oC`
`T_i =21^oC`
`C_p=4.18J(g^oC)`

`Q=576g(58^oC-21^oC)4.18J/(g^oC)`

`Q=576cancel(g)(37(cancelC))4.18J/cancel(g^oC)`

`Q=89,084.16 J`
