Given 28.2 grams of an unknown substance, if the substance absorbs 2165 joules of energy and the temperature increases by 35 Kelvin, what is the specific heat of the substance?

2.14 x 106 J/g·K

2.19 x 100 J/g·K

5.73 x 10-4 J/g·K

2.69 x 103 J/g·K
Can someone show the steps of how to solve these type of questions?

do u knw the equation for delta h?

anonymous · Answer

I know nothing that has to do with this question.

apoorvk · Answer

Specific heat of a substance is the amount of heat required to raise the temperature of 1 g of a substance by 1K.

Helps?

anonymous · Answer

Somewhat, I understand the concept. I just have no idea what he formula for that would be? Or is there even a formula?

apoorvk · Answer

There is a formula umm.. but why do you need it when you can create one from the definition above - or just solve it using the definition.

anonymous · Answer

c=q/mdeltaT, there should be another temperature

apoorvk · Answer

you don't need another temperature @Farrah , the delta means 'change' in temperature - which is exactly what is stated in the question - the 'increase in temperature is 35K'

anonymous · Answer

How would I make an equation out of the number given in the question when the answers are different numbers? I don't see how I can get any of the numbers in the answers out of what they provide by the question. Which what I'm trying to figure out.

apoorvk · Answer

okay.
so, 2165 J is required for raising the temp. by 35K right? then how much is required for raising the temperature by 1K?

apoorvk · Answer

just follow what i am asking you to do.

61.86?
