Liquid nitrogen boils at –195.8°C. Express the boiling point of liquid nitrogen in kelvin

Chemistry

Answer:

\boxed {\boxed {\sf 77.35 \ K}}

Explanation:

The Celsius and Kelvin scales are used to measure the temperature of matter.  Their scales and unit differences are the same (1 K increase = 1 °C increase), but they have different starting points.

So, the conversion is quite simple and only requires addition because of the different starting points. The formula is:

T_K = T_C+ 273.15

The boiling point of liquid nitrogen is -195.8 °C. We can substitute this value into the formula.

T_K= -195.8 + 273.15

T_K= 77.35 K

The boiling point of liquid nitrogen is 77.35 Kelvin.

What is the velocity of a 0.5-kg ball<br> that has a momentum of 3 kg.m/s?
maria [59]

Answer:

6m/s

Explanation:

Data obtained from the question include:

Mass = 0.5kg

Momentum = 3 kg.m/s

Velocity =.?

Momentum is simply the product of mass and velocity as shown by the equation below:

Momentum = Mass x Velocity

Velocity = Momentum /mass

Velocity = 3kg.m/s / 0.5kg

Velocity = 6m/s

Therefore, the velocity of the ball is 6m/s
