Answer:

(C) Boyle's law

Explanation:

According to Boyle's law when we kept the temperature as constant and is we decrease the pressure of the gas then the volume of the gas is increases it means that at pressure and volume are inversely proportional to each other when we take temperature as constant.

So for the given statement Boyle's law will be correct option

So option (c) will be correct option

Which describes how the talk test is used to check exercise intensity?
Masteriza [31]
I believe if you are so out of breath that you cannot talk while exercising, your exercise level is too intense. Intensity in exercise is how hard you work out. For example sprinting up a flight of stairs over and over again would be a high intensity workout. To measure the intensity of exercise one method would be to monitor the heart rate of the individual undertaking the exercise

A two-liter bottle is one-fourth full of water and three-quarters full of air. The air in the bottle has a gage pressure of 340
Fantom [35]

Answer:

The value is     P_G  =  2.925 *10^{5} \  Pa

Explanation:

From the question we are told that

   The  volume of the bottle is  v  =  2 \  L  =  2 *  10^{-3} \  m^3

   The gauge pressure of the air is P_g  =  340 \  kPa  =  340 *10 ^{3}  \  Pa

   

Generally the volume of air before the bottle is turned upside down is  

      V_a  =  \frac{3}{4}  * V

       V_a  =  \frac{3}{4}  *  2 *10^{-3}

       V_a  =  0.0015 \  m^3 }

Generally the volume air when the bottle is turned upside-down is

      V_u  =  \frac{5}{6}  *  2 *10^{-3}

       V_u  =  0.00167 \  m^3

From the the mathematical relation of adiabatic process we have that

     P_g *  V_a^r  =  P_G *  V_u^r

Here r is a constant with  a value  r =  1.4

So

      340 *10 ^{3}  *  0.0015^{1.4}  =  P_G *  0.00167^{1.4}

        P_G  =  2.925 *10^{5} \  Pa
