Acar tire is filled with air at pressure 325000 pa at 303 k. when the tire cools, its pressure reduces to 299000 pa. what is the new temperature of the tire?

new temperature of the tire will be 278.76 K

Explanation:

when the temperature increases, the particles will have greater kinetic energy and also the pressure will be increase for the gas particles.

so when the temperature increases, pressure  will also increase  and vice versa

 T is directly proportional to P

T1  = initial temperature= 303 k

P1= Initial pressure =  325000 pa

T2= Final temperature=  ?

P2= Final pressure =   299000 pa

mathematically

P1/T1= P2/T2

T2= P2 x T1/P1

T2 = 299000 x 303/ 325000=  278.76 k

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
