how many kilojoules are required to raise the temperature of a 150. g sample of silver from 25 °C to 135 °C? Silver has a specific heat of 0.235 J/g °C.

Please type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.

How many kilojoules are required to raise the temperature of a 150. g sample of silver from 25 °C to 135 °C? Silver has a specific heat of 0.235 J/g °C.

The temperature rise is 110C.

Multiply that by the mass and specific heat.

You may have to convert joules to kilojoules. I assume you know how to do that

Thank you, I've done this and submitted it only keep getting it incorrect, so I was wondering what I could be doing wrong.

Thank you

Unless you shown your work I cannot advise on where you might have made a mistake, or if perhaps the "answer book" number is wrong.

Remember that they are asking for the answer in kilojoules, not joules. Use three significant figures

If 57 j of heat are added to an aluminum can with mass of 17.1 g what is it's temperature change?
