If the pressure of a gas sample is quadrupled and the absolute temperature is doubled. True or False
Vanyuwa [196]

The given statement"If the pressure of a gas sample is quadrupled and the absolute temperature is doubled" is false.

Answer: Option B

<u>Explanation:</u>

As we know the direct relationship between Pressure and Temperature by the Gay-Lussac’s Law,

                     P_{1} T_{1}=P_{2} T_{2}

From this, we get,

                     \frac{P_{1}}{T_{2}}=\frac{P_{2}}{T_{1}}

                     T_{2}=\frac{P_{1} T_{1}}{P_{2}}

So, according to given statement, we have P_{2} = 4 P_{1}

Then from the above expression, we can find out the value of T_{2} when pressure increased by 4 times of initial pressure as,

                     T_{2}=\frac{P_{1} T_{1}}{4 P_{1}}

Hence, we get,

                      T_{1}=4 T_{2}

Hence, from the above expression we can say that as we increase the pressure four times, the temperature does not get doubled. So, the given statement in the question is false.

Pls help waves for physics
djverab [1.8K]

Answer:

b) 252 Hz or 260 Hz

c) 0.25 s

Explanation:

b) The frequency of the beats is 4 Hz, and one tuning fork has a frequency of 256 Hz.  Therefore, the second tuning fork is either 4 Hz lower or 4 Hz higher.

f = 252 Hz or 260 Hz

c) Period is the inverse of frequency.

T = 1/f

T = 1 / (4 Hz)

T = 0.25 s
