A cylinder contains 3.5 L of oxygen at 350 K and 2.7 atm . The gas is heated, causing a piston in the cylinder to move outward.

The heating causes the temperature to rise to 620 K and the volume of the cylinder to increase to 9.1 L.What is the gas pressure? P= _____atm

Answer:

The pressure is P_2  =  1.84 \  a.t.m

Explanation:

From the question we are told that

   The first  volume of  is  v_1  =  3.5 \ L

   The first  pressure is  P_1  =  2.7 \ a.t.m

   The first  temperature is  T_1  =  350 \ K

    The  new temperature is  T_2  =  620 \ K

     The  new volume is  V_2  =  9.1 \ a.t.m

Generally according to the combined gas law we have that

      \frac{P_1 V_1  }{T_1 }  =  \frac{P_2  V_2 }{T_2 }

=>  P_2  =  \frac{P_1  *  V_1  *  T_2 }{T_1  *  V_2 }

=>    P_2  =  \frac{ 2.7  *  3.5   *  620 }{ 350  *  9.1 }

=>  P_2  =  1.84 \  a.t.m

The mass of an object is 60kg on the surface of the earth what will be its weight on the surface of the moon
iris [78.8K]

Answer:

Wm = 97.2 [N]

Explanation:

We must make it clear that mass and weight are two different terms, the mass is always preserved that is to say this will never vary regardless of the location of the object. While weight is defined as the product of mass by gravitational acceleration.

W = m*g

where:

m = mass = 60 [kg]

g = gravity acceleration = 10 [m/s²]

But in order to calculate the weight of the body on the moon, we must know the gravitational acceleration of the moon. Performing a search of this value on the internet, we find that the moon's gravity is.

gm = 1.62 [m/s²]

Wm = 60*1.62

Wm = 97.2 [N]
