Question

When 45 g of alloy, at 25 C,are dropped into 100.00 g of water, the alloy absorbs 956 J of heat. If the final temperature of the alloy is 37 C, what is its specific heat capacity?

Answer 3

Think unit of specific heat capacity: kg/kJ K
It tells energy which is needed to rise temperature
By one Kelvin (or degrees of C) for one kilogram
Of substance.

It can also be g / J K, it would be better in this case.

Now think, how you get right unit from adding
Values.

Answer 4

This looks like a job for \[Q = mc\Delta t\]
We know \(m\), we know \(Q\), we know \(\Delta t\) — solve for \(c\) and plug in the numbers.
