The building is in solid phase. Its molecules are arranged in a ver compact manner that is why it takes a definite shape and volume. When it is heated, the kinetic energy of the molecules increases. This is characterized by more frequent collisions. The rise in temperature causes the molecules to move rapidly by vibrating. When it reaches an amount of energy that causes the solid to change phase, this is called the latent energy. The molecules break their form and move farther away from each other until it resembles that of a liquid melting. This phase change is known as melting. The energy that must be reached to achieve melting is the latent heat of fusion.

The electric potential difference of a 150 µF capacitor is measured across the terminals of the capacitor and found to be 5 volt

Lapatulllka [165]

The potential energy stored in a capacitor is given by:
$U= \frac{1}{2}CV^2$
where
C is the capacitance of the capacitor
V is the potential difference across the plates of the capacitor

In our problem,
$C=150 \mu F= 150 \cdot 10^{-6} F$
$V=5 V$
Therefore, the potential energy of the capacitor is
$U= \frac{1}{2}(150 \cdot 10^{-6}F)(5 V)^2 = 1.88 \cdot 10^{-3}J$

An object is 27.0 cm from a concave mirror of focal length 15.0 cm. find the image distance.

pantera1 [17]

The distance of the Image will be -33.75 cm

A concave mirror has an inward-curving reflecting surface that faces away from the light source. Unlike convex mirrors, a concave mirror's image forms a variety of images based on the object's proximity to the mirror.

Given that, an object placed 27 cm from a concave mirror having the focal length of 15 cm

We have to find distance of the Image

Using Mirror Formula:

1/f = 1/v + 1/u

Where,

f = focal length

v = Image distance from the mirror

u = object distance from the mirror (concave)

Substitute the known values in the above formula to find the value of 'v' i.e. from the mirror.

1/(-15) = 1/v + 1/(-27)

1/(-15) = 1/v - (1/27)

1/v = -0.029

v = -33.75 cm

Therefore the distance of the Image will be -33.75 cm

d) To calculate air pressure, the volume occupied by air is assumed constant. Why is this incorrect? Explain how the vapor press

Aleks [24]

Answer:

the volume occupied by air is not constant because as we add ethanol in it it will keep decreasing.

vapor pressure calculated and clausius-Claperon plot are affected because volume and vapor pressure are directly proportional.

Explanation:

by charle's law volume and temperature are directly proportional and vapor pressure is directly proportional to temperature thus volume and vapor pressure are also directly proportional by this relation
