Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

I do not know how to solve this proble and was wondering if you could offer some guidance.

Question:

How long after it is turned on will a 100-W electric

heater take to bring a quart of water to a boil from room

temperature 20 deg C?

Here's what I know:

[tex]T_i=20[/tex]

[tex]T_f=100[/tex]

[tex]\Delta T=80[/tex]

[tex]100W = \frac{100J}{1s}[/tex]

Thanks!
