Answer:
One can of cola contain 0.16 kcal of carbohydrates.
Explanation:
Given data:
mass of cola can = 40 g
kilocalories of carbohydrates = ?
Solution:
we know that there are 4 cal of carbohydrates per gram.
40 g × 4 cal/g = 160 cal
Now we will convert calories into kilocalories. There are 1000 calories in one kilocalories so,
160/1000 = 0.16 kcal
so, one can of cola contain 0.16 kcal of carbohydrates.
Answer:
852000 J
Explanation:
The following data were obtained from the question:
Mass (M) = 600 g
Change in temperature (ΔT) = 2 °C
Specific heat capacity (C) = 710 J/g℃
Heat transfered (Q) =?
Thus, we can obtain the the heat transfered to the diamond by using the following formula:
Q = MCΔT
Q = 600 × 710 × 2
Q = 852000 J
Therefore, the energy transfered to the diamond by heat is 852000 J
