Answer:

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)
