If the mass of one liter (L) of water is 1 kg, what is the weight of one liter of water?

Respuesta :

The following expression gives relationship of weight and mass:
Weight = mass * gravitational acceleration = mg

Since
1 L = 1 kg

Then weight 1 L of water = 1*9.81 = 9.81 N

Answer:

9.8 N

Explanation:

We can calculate the weight of one liter of water from its mass, using Newton's second law:

[tex]F=ma[/tex]

The water weight (W) is a measure of the gravitational force acting on the water. Thus, acceleration (a) becomes the acceleration of gravity (g):

[tex]W=mg\\W=1kg*9,8\frac{m}{s^2}\\W=9.8N[/tex]
