Question

which of the following is an expression of boyles law?
a. \\( \frac { p } { t } = \text { constant } \\)
b. \\( p t = \text { constant } \\)
c. \\( p v = \text { constant } \\)
d. \\( \frac { v } { t } = \text { constant } \\)

Explanation:

Boyle's law states that for a given mass of an ideal gas at a constant temperature, the product of pressure ($P$) and volume ($V$) is constant.

• Option A: $\frac{P}{T}=$ constant is related to Gay - Lussac's law (when volume is constant).
• Option B: $PT =$ constant is not a standard gas law expression.
• Option C: $PV=$ constant is Boyle's law.
• Option D: $\frac{V}{T}=$ constant is Charles's law (when pressure is constant).

Answer:

C. $PV =$ constant
