Question

Как изменится масса сосуда, в который налили керосин объемом 2 дм^3?

Answer 1

2 дм³ = 2*10⁻³ м³
m=pV=800 кг/м³ * 20*10⁻³ м³ = 16 кг.
Масса сосуда увеличится на 16 кг.

Answer 2

Change in Mass of a Container When Filled with Kerosene

When a container is filled with kerosene, the change in mass can be calculated based on the density of kerosene and the volume of the container. The formula to calculate the change in mass is:

Change in Mass = Density of Kerosene × Volume of Kerosene

Given that the volume of kerosene is 2 dm^3, we can use this formula to calculate the change in mass.

The density of kerosene is approximately 0.8 kg/dm^3.

Using the formula, the change in mass can be calculated as follows:

Change in Mass = 0.8 kg/dm^3 × 2 dm^3 = 1.6 kg

Therefore, when a container is filled with kerosene with a volume of 2 dm^3, the change in mass of the container will be approximately 1.6 kg.
