in the presence of sun light.
The object that shows fast motion is said to have a higher speed while the one with slow motion is said to have a slow speed.
Hope that helps it was on googIe
The new volume if the balloon is cooled at constant pressure is 3.98 L.
Charles's law, states that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature if the pressure remains constant.
The new volume is calculated using the Charles law formula
V₁ / T₁ = V₂ / T₂
where,
V₁ = The initial volume of air = 4.24 l
T₁ = 23.00 °C into kelvin = 23 +273 =296 K
T₂ = 5.00 °C into kelvin = 5.00 + 273 = 278 K
V₂ = ?
By making V₂ subject the subject of the formula by multiplying both sides by T₂
V₂ = ( V₁ × T₂ ) / T₁
V₂ = (4.24 L × 278 K) / 296 k
= 3.98 L
Therefore, the new volume, if the balloon is cooled at constant pressure, is 3.98 L.
An air-filled balloon will contract when chilled and expand when heated. This occurs because the gas that makes up the air within the balloon expands when it is warm and contracts when it is cool.

Answer:
The answer to your question is 160 g of Calcium
Explanation:
Data
mass of Calcium = ?
mass of Hydrogen = 8 g
reactant = HCl
Process
1.- Write the balanced chemical reaction
Ca + 2HCl ⇒ CaCl₂ + H₂
2.- Look for the atomic number of Calcium and hydrogen
Calcium = 40 g
Hydrogen = 1 x 2 = 2 g
3.- Use proportions to calculate the mass of calcium needed.
40 g of Calcium ---------------- 2 g of hydrogen
x ----------------- 8 g of hydrogen
x = (8 x 40) / 2
x = 320/2
x = 160 g of Calcium
