Answer:
Endothermic
Explanation:
Storing sugar for later use is an example of an endothermic reaction because that energy is being absorbed.
1.8 L
<h3>
Explanation</h3>
The volume of a gas, V, is inversely proportional to the pressure on it, P. That is:
V₁ · T₁ = V₂ · T₂.
Rearranging gives:
V₂ = V₁ · T₁ / T₂ = 4.2 × (101 / 235) = 1.8 L
V₁ = initial Volume of the balloon after it is blown up = 365 L
V₂ = new Volume of the balloon after it is taken outside = ?
T₁ = initial temperature of the balloon = 283 K
T₂ = new temperature of the balloon = 300 K
using the equation
V₁/V₂ = T₁/T₂
365/V₂ = 283/300
V₂ = 387 L
