Select the correct statement to describe when a sample of liquid water vaporizes into water vapor

Physics
1 answer:
sweet-ann [11.9K]4 years ago
8 0

Answer:

This procces is called evaporation.

Explanation:

When you have liquid water that is transformed into steam, a phase change is called evaporation. The temperature for the evaporation of water depends on the pressure, for example for water at atmospheric pressure the temperature of evaporation is equal to 100°C. as the pressure increases are achieved evaporation temperatures higher. When that happens, the phase change temperature of the water is not increasing, as the process that takes place is the transfer of latent heat and applies only to changes of phase, that is to say at atmospheric pressure when it has 100% of the steam this will be at 101°C.

A dock worker applies a constant horizontal force of 81.0 N to a block of ice on a smooth horizontal floor. The frictional force
AnnZ [28]

Answer:

The correct answer is:

(a) 84.240 kg

(b) 24.038 m

Explanation:

The given values are:

Force,

F = 81.0 N

Distance,

S = 13.0 m

Time,

t = 5.20 s

As we know,

The acceleration of mass will be:

⇒  a=\frac{2S}{t^2}

On substituting the given values, we get

⇒     =\frac{2\times 13.0}{(5.20)^2}

⇒     =\frac{26}{27.04}

⇒     =0.961538 \ m/s^2

(a)

The mass of the block will be:

⇒  m=\frac{F}{a}

On substituting the given values, we get

⇒       =\frac{81.0}{0.961538}

⇒       =84.240 \ kg

(b)

The final velocity after a given time i.e.,

t = 5.00 s

⇒  v=at

On substituting the values, we get

⇒     =0.961538\times 5.00

⇒     =4.8076 \ m/s

In time, t = 5.00 s

The distance moved by the block will be:

⇒  d=vt

On putting the values, we get

⇒     =4.8076\times 5.00

⇒     =24.038 \ m

In a laboratory, you determine that the density of a certain solid is 5.23×10−6kg/mm3. Convert this density into kilograms per c
madam [21]

Answer:

1 mm^3 = 1.0 x 10^-9 m³

Hence;

5.23 x 10^-6 kg/mm^-3 = (5.23 x 10^-6 kg)/ 1x10^-9 m³

= 5230 kg/m³

If a boulder has a mass of 50 kg and a potential energy of 490 j what is the height of the boulder
Mkey [24]
Potential energy = mass x g x height.
height = potential energy/mass x g
acceleration due to gravity on earth is 9.8 m/s
filling in your variables gives us:
490/50 x 9.8 = 1 meter
