Question #8f2db

Answer 1

The change in temperature is `89^@"C"`.

Explanation:

The equation to use is:

`Q=m*c*DeltaT`,

where Q is the energy in Joules that is lost or gained, `m` is mass, `c` is specific heat, and `DeltaT` is change in temperature.

Solution
Rearrange the equation to isolate `DeltaT`. Substitute the given values into the equation and solve.

`DeltaT=(Q)/(m*c)`

`DeltaT=(9612color(red)cancel(color(black)"J"))/(120color(red)cancel(color(black)("g"))xx0.899color(red)cancel(color(black)("J"))/(color(red)cancel(color(black)("g"))""^@"C"))="89"^@"C"` (rounded to two significant figures)
