If 200 g of iron absorbs 22,000 cal of heat, what will be the change in temperature (specific heat of iron =0.11 cal/g°C).

Question

perl · Answer

we can use the equation
 Q = mass * specific heat * change in Temperature

So, could you help me work this exact problem?

perl · Answer

We can plug into the formula above

22000 = 200 * (0.11) * delta T

and solve for delta T

anonymous · Answer

Okay, so then we would have to do the opposite and divide correct?
so it would be 22000/ 200(0.11) = delta T?

anonymous · Answer

Sorry, I'm not very good
 at this stuff

perl · Answer

yes thats correct

perl · Answer

just be careful with the parentheses

perl · Answer

22000/ ( 200(0.11) ) = delta T

anonymous · Answer

so typing that into my TI83, I would type it exactly as you just listed it?

perl · Answer

yes you can do that. or 
22000 / ( 200 * 0.11)

anonymous · Answer

I got 1000, is that correct?

perl · Answer

yes

perl · Answer

so there will be a change of 1000 degrees Celsius temperature
