Given :
A gas with a volume of 2 L at 25°C is placed into a container that is 4 L.
To Find :
The new temperature of the gas.
Solution :
Since, their is no information regarding pressure. We will assume that pressure is constant.
Now, we know when at constant pressure, volume is directly proportional to volume.
Therefore, the new temperature of the gas is 596 - 273 K = 323 K.
All solids have an orderly internal structure with repeating bonding patterns between atoms, ions, or molecules. They are called crystal lattices. They are a 3-dimensional arrangement of atoms inside a crystal. The volume of this crystal is:
<span>
Volume = 2.44 × 10^–2 m x 1.4 × 10^–3 m x 8.4 × 10^–3 m = </span>2.87 x 10^-7 m^3
Answer:
Molecular Formula = C₆H₁₂O₆
Solution:
Molecular formula is calculated by using following formula,
Molecular Formula = n × Empirical Formula ---- (1)
Also, n is given as,
n = Molecular Weight / Empirical Formula Weight
Molecular Weight = 180.2 g.mol⁻¹
Empirical Formula Weight = 12 (C) + 2 (H₂) + 16 (O) = 30 g.mol⁻¹
Son
n = 180.2 g.mol⁻¹ ÷ 30 g.mol⁻¹
n = 6
Putting Empirical Formula and value of "n" in equation 1,
Molecular Formula = 6 × CH₂O
Molecular Formula = C₆H₁₂O₆

Answer:
Explanation:
Potential energy is the energy possessed by an object due to its position. For example, when the ball starts to move from its resting position then the ball gains kinetic energy. Thus, as gravity makes an object fall down toward the ground, potential energy becomes kinetic energy.
