How much energy is required to raise 10 grams of water by 10 degrees Celsius? (in Joules)
2 answers:
<u>Answer:</u> The amount of heat required by water is 418.6 J
<u>Explanation:</u>
To calculate the heat absorbed by water, we use the equation:
where,
q = heat absorbed
m = mass of water = 10 g
c = heat capacity of water = 4.186 J/g°C
= change in temperature = 10°C
Putting values in above equation, we get:
Hence, the amount of heat required by water is 418.6 J

Answer:
=> 2.8554 g/mL
Explanation:
To determine the formula to use in solving such a problem, you have to consider what you have been given.
We have;
mass (m) = 16.59 g
Volume (v) = 5.81 mL
From our question, we are to determine the density (rho) of the rock.
The formula:
Substitute the values into the formula:
= 2.8554 g/mL
Therefore, the density (rho) of the rock is 2.8554 g/mL.
