<u>Answer:</u> The heat required will be 58.604 kJ.
<u>Explanation:
</u>
To calculate the amount of heat required, we use the formula:
Q= heat gained or absorbed = ? J
m = mass of the substance = 100 g
c = heat capacity of water = 4.186 J/g ° C
Putting values in above equation, we get:
Q = 58604 Joules = 58.604 kJ (Conversion factor: 1 kJ = 1000J)
Thus, heat released by 100 grams of ice is 58.604kJ.
Answer:
"Heat of combustion"
Explanation:
A physical property is characteristic of a substance that can be observed or measured without changing its chemical composition, such as color, molecular weight, and volume. A chemical property can only be observed or measured by changing the chemical composition of the substance, such as reactivity, flammability and oxidation states.
Hope this helps! :)
I want to say 8 but i'm not sure. I just did a lesson on this and my notes say it could be 8 but then again I'm not sure.
I’m not sure but I think the answer is substance . Because you can change the temperate of a substance but it will still be that substance . You can change all of these things except the substance itself
