at constant atmospheric pressure, the temperature of a gas that occupies the volume of 5.30 L is 298 K. what is the temperature
harkovskaia [24]

Answer:

The new temperature of the gas is 427K

Explanation:

In this case we use Charles's Law according to which the volume and temperature of a certain amount of gas are related, keeping the pressure constant.

V1 / T1 = V2 / T2

5,30L/298K=7,60L/T2

T2=7,60L/(5,30L/298K)=427,32K

Using the Acceleration Equation
Maru [420]

Answer:

Change in velocity (\Delta v) is acceleration (a) times time (t)

Acceleration a=1.2\ m/s^{2}

Time t=10\ s

So \Delta v=at=1.2\ m/s^{2}*10\ s=12\ m/s

The initial velocity is then 16\ m/s-12\ m/s=4\ m/s

Easy Answer: 4m/s
