quester [9]

Answer: 888.45 K or 615.3 °c

Explanation:

According to Gay Lussacs law which states that at constant volume, pressure of an ideal gas is directly proportional to it's absolute temperature.

P/T = Constant

Therefore, P1/T1 = P2/T2

P1 = 6.7 atm

T1= 23°c = 273.15 + 23 = 296.15K

Since P2 is tripled, then,

P2 = 6.7 x 3= 20.1 atm

T2 = (20.1 x 296.15) ÷ 6.7

T2 = 888.45 K

Or in celcius 615.3°c

What is the momentum of a 1.5 * 10 ^ 3 - kil kilogram car as it travels at 30. meters per second due east for 60. seconds ?
serg [7]

Answer:

45000kgm/s due east

Explanation:

Given parameters:

Mass of the car  = 1.5 x 10³kg

Velocity  = 30m/s

Time taken  = 60s

Unknown:

Momentum  = ?

Solution:

Momentum is the quantity of motion a body possess,

     Momentum  = mass x velocity

So;

  Momentum  = 1.5 x 10³ x 30  = 45000kgm/s due east
