In the formulas for latent heat of fusion and latent heat of vaporization, what does Q represent?

Physics
1 answer:
Leto [7]3 years ago
3 0

Answer:

the amount of heat of energy released or absorbed by a substance.

Explanation:

Mathematically, latent heat of fusion is given by the formula;

Q = mL

Where;

Q is the quantity of heat energy measured in Joules.

m is the mass measured in kilograms.

L is the specific heat latent heat of fusion.

In the formulas for latent heat of fusion and latent heat of vaporization, Q represents the amount of heat of energy released or absorbed by a substance.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

How much heat is contained in 100 kg of water at 60.0 °C?
attashe74 [19]
First we need to write down heat capacity for water which is constant.
cp=4186 J/(kg*K)

The equation for Energy that we will be calculating is:

E=cp*m*T
where m is mass and T is absolute temperature (273,15 + 60 in this case). Replacing all the values in equation we get:

E = 4186*100*333,15 = 139 456 590 J

An athlete completes 1 laps around a track with a radius of 25 meters in 180 seconds. What is the magnitude of the athlete's tan
DanielleElmas [232]

Answer:

0.872<em>m/s</em>

Explanation:

Tangential velocity is given by the formula,

v= 2\pi r/ t

In the question given,

radius= 25meters

time= 180secs

pie= 3.14

number of laps= 1

The magnitude of tangential velocity equals;

\frac{1lap* 2 *3.14 *25m}{180secs}

<em>v </em>= 157<em>m</em>/180<em>secs</em>

Therefore, the magnitude of the tangential velocity

=0.872<em>m/secs</em>
