Therefore, the volume of the gas at temperature 100°C is 4.62L
<u />
<u>Explanation:</u>
Given-
Volume, V1 = 4L
Temperature, T1 = 50°C = 50 + 273K = 323K
Temperature, T2 = 100°C = 100 + 273K = 373K
Volume, V2 = ?
Using Charles law:
V1/T1 = V2/T2
4/323 = V2/373
V2 = 4.62L
Therefore, the volume of the gas at temperature 100°C is 4.62L

Answer:
d) The speed of the astronaut
Explanation:
The sentence describes the speed of the astronaut. This speed value is 10meters per minute. 
Now let us understand why; 
- Speed is the distance divided by time. It is a scalar quantity without regard for direction but it has magnitude. 
- The value 10meters per minute clearly shows this instance. We do not know the direction the astronaut is moving towards. 
- Velocity, like speed is the displacement of a body with time. It is a vector quantity and it shows the direction of motion. 
- For example, 10m/s due west is a velocity value because we know the direction. 
Therefore, since there is no directional sense, the value indicates speed.
