Answer:
= 9,593.1 Joules
Explanation:
Heat absorbed by water is equivalent to heat released by copper.
Heat absorbed is given by;
Q = mcΔT
where m is the mass, c is the specific capacity and ΔT is the change in temperature.
Therefore;
Since dnsity of water is 1 g/mL, and specific heat capacity is 4.18 J/g°C while the change in temperature is (75-24) = 51°C.
Heat absorbed by water = 45 g × 4.18 J/g°C × 51
= 9,593.1 Joules
Therefore, the heat released by copper is 9,593.1 Joules
So that every measurement is accurate.. hope this helps
Answer:
q=mAHf
Explanation:
When water change form from solid(ice) to liquid, it will need heat that depends on the heat of fusion(Hfus). If the form changed from liquid to gas it will use the heat of vaporization(Hvap) instead. The heat of fusion usually written just AT
q=MCAT is used to calculate heat when temperature change(AT = delta T= difference in temperature)
q=mAHvap is wrong because you need if the form change from liquid to gas
q=mc^2 is wrong because it describes the relation of mass and energy, not the form.
The answer should be q=mAHf
Joshua saw the rising batter form the cake in the oven.
He saw that because of the reaction of baking soda/powder with the liquid in the batter.
First you have to tell people what are the choices
