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.

Juan's family and Ethan's family go to a food stand.

Rasek [7]

Answer:

1 hotdog is $3.5.

1 drink is $2.

Step-by-step explanation:

18.50= 3x+4y(times 5)

25.50=5x+4y(times -3)

92.5=15x+20x

-76.5=-15x+-12y

16=-8y

2=y

18.50=3x+4(2)

10.50=3x+8

10.50=3x

3.5=x
