According to Charles's law, if the pressure is held constant, the volume of a gas varies directly with the temperature measure

Ksju [112]

Answer:

V₂ = 252 cm³

Step-by-step explanation:

Charles's law = If the pressure is held constant, the volume of a gas varies directly with the temperature measured on the Kelvin scale.

Mathematically, $V=kT$

$\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}$

We have, V₁ = 192 cm³, T₁ = 112 K, T₂ = 147 cm³, V₂ = ?

Using the above relation of Charles's law :

$V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{192\times 147}{112}\\\\V_2=252\ cm^3$

So, the new temperature is 252 cm³.

2x+1=5x-8 Solving Equations with Many or No Solutions

aliina [53]

Hello!

$\large\boxed{x = 3}$

2x + 1 = 5x - 8

Solve by subtracting both sides by 2x:

2x - 2x + 1 = 5x - 2x - 8

1 = 3x - 8

Add 8 to both sides:

1 + 8 = 3x - 8 + 8

9 = 3x

Divide both sides by 3:

9/3 = 3x/3

x = 3
