Answer 1

um what is the equation again? I need to see the equation in order to help you.

Answer 2

is it q = mc*deltaT?

Answer 3

I believe so

Answer 4

so we have everything here...

m = mass
c = specific heat
t_o and t_f are given as well

Answer 5

deltaT = Tf - Ti so what is Ti?

Answer 6

Ti = t_o

Answer 10

Okay. So

The equation is \(Q = mCp(deltaT) \)

We already know that
\(Q\) = heat required
\(m\) = mass of silver = 24.7 kg (given)
\(Cp\) = specific heat = 236 J/kg-C (given)
\(delta~ T\) = temperature change = 30 - 14 = 16 C

Now we just want to substitute the values. So can you solve this: \(Q = 24.7*236*16 \).

What do you get?

Answer 13

now just convert `93267.2` to scientific notation

Answer 14

Something like `5.93 E 4 J` means `5.93 * 10^4 joules`

5.93 * 10^4 = 59,300

notice how the decimal point moved 4 spots to the right and how the exponent is +4
