Answer:
No heat is released.
Explanation:
A substance absorbs heat when it melts.
The formula for the heat absorbed is
Data:
m = 10 g
\Delta_{fus) H=\text{334 J/g}
Calculations:
A helium balloon displaces the amount of air. The weight of the helium in the balloon + the balloon fabric = lighter than the air that it displaces. Helium is lighter than air, so therefore, if it's in a balloon, the balloon will float.
Answer:
10.051kg of gold is the mass in kilograms
Explanation:
The density of gold is 19.3g/mL. To solve this question we need to convert the volume of the block of gold to grams using its density. Then, we must convert grams to kilograms using the equivalence factor (1000g = 1kg):
<em>Mass in grams:</em>
520.79mL * (19.3g / mL) = 10051g of gold
<em>Mass in kilograms:</em>
10051g of gold * (1kg / 1000g) = 10.051kg of gold
