The amount of heat required to raise 200 g of aluminum by 10 degrees celsius if its specific heat is 0.897 J/gC ?

I need help. This is all confusing.

m=200 g

c=0.897 J/g°C
ΔT=10°C
Calculate heat required, ΔQ using

ΔQ=mcΔT

Oh, okay. You multiply the numbers. I was dividing it for some reason. Thank you, you are a lifesaver.

As Damon said, check the units.

If you divide, the units do not give joules.

You are welcome :)

I can definitely help you with this problem! To find the amount of heat required to raise the temperature of a substance, you can use the formula:

Q = m * c * ΔT

Where:
Q represents the amount of heat
m is the mass of the substance (in grams)
c is the specific heat capacity of the substance (in J/g°C)
ΔT is the change in temperature (in °C)

In your case, you are given the following values:
m = 200 g (mass of aluminum)
c = 0.897 J/g°C (specific heat of aluminum)
ΔT = 10°C (change in temperature)

Now let's plug in these values into the formula:

Q = 200 g * 0.897 J/g°C * 10°C

First, multiply the mass (200 g) by the specific heat (0.897 J/g°C):
Q = 179.4 J/°C * 10°C

Then, multiply the result by the change in temperature (10°C):
Q = 179.4 J/°C * 10°C = 1794 J

Therefore, the amount of heat required to raise the temperature of 200 g of aluminum by 10 degrees Celsius is 1794 J.

Just look at the units:

Joules = Joules/gram deg C * grams * deg C

grams cancel
deg C cancels
left with Joules

= .897 * 200 * 10 Joules

= 1794 Joules
