If 100.00 J are added to 20.0 g water at 30.0°C, what will be the final temperature of the water?
The final temperature of the water will be 31.2 °C.
The formula for the heat gained or lost by a substance is
#color(blue)(bar(ul(|color(white)(a/a)q = mcΔTcolor(white)(a/a)|)))" "#
We can rearrange this equation to get
#ΔT = q/(mc)#
In this problem,
