aleksandrvk [35]

Answer:

1.005 cm³

Explanation:

Using Ideal gas equation for same mole of gas as

\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}

Given ,  

V₁ = 0.650 cm³

V₂ = ?

P₁ = 1.54 atm

P₂ = 1.01 atm

T₁ = 12°C

T₂ = 16 ºC

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T₁ = (12 + 273.15) K = 285.15 K  

T₂ = (16 + 273.15) K = 289.15 K  

Using above equation as:

\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}

\frac {{1.54}\times {0.650}}{285.15}=\frac {{1.01}\times {V_2}}{289.15}

Solving for V₂ , we get:

<u>V₂ = 1.005 cm³</u>

Veseljchak [2.6K]

Answer:

Speed of light

Explanation:

The value 3.0 x 10⁸m/s is taken as the speed of light.

It is a constant.

  • It implies that light travels a distance of 3 x 10⁸ in just one second.
  • This value is for the speed of light in a vacuum when there are not particles obstructing its movement.
  • The speed of electromagnetic radiations in free space is also taken as the speed of light.
