What is the difference between temperature and heat???
olga55 [171]

Answer:

Difference between heat and temperature in tabular form

Heat vs Temperature

1.Heat is a form of energy that can transfer from a hot body to a cold body. and Temperature is the degree of hotness and coldness of a body.

2.Heat is the total kinetic energy and potential energy obtained by molecules in an object. and Temperature is the average K.E of molecules in a substance.

3.Heat flows from hot body to cold body. It rises when heated and falls down when an object is cooled down and It has a working ability. It does not have the working ability

.

4.Its SI unit is “Joule” and Its SI unit is “Kelvin”.

5.It is measured by the calorimeter and It is measured by the thermometer

.

6.It is represented by “Q”. and It is represented by “T”.

Explanation:

A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. ... A simple calorimeter just consists of a thermometer attached to a metal container full of water suspended above a combustion chamber.

A tank contains gas at 13.0°C pressurized to 10.0 atm. The temperature of the gas is increased to 95.0°C, and half the gas is re
fomenos

Answer:

The pressure of the remaining gas in the tank is 6.4 atm.

Explanation:

Given that,

Temperature T = 13+273=286 K

Pressure = 10.0 atm

We need to calculate the pressure of the remaining gas

Using equation of ideal gas

PV=nRT

For a gas

P_{1}V_{1}=nRT_{1}

Where, P = pressure

V = volume

T = temperature

Put the value in the equation

10\times V=nR\times286....(I)

When the temperature of the gas is increased

Then,

P_{2}V_{2}=\dfrac{n}{2}RT_{2}....(II)

Divided equation (I) by equation (II)

\dfrac{P_{1}V}{P_{2}V}=\dfrac{nRT_{1}}{\dfrac{n}{2}RT_{2}}

\dfrac{10\times V}{P_{2}V}=\dfrac{nR\times286}{\dfrac{n}{2}R368}

P_{2}=\dfrac{10\times368}{2\times286}

P_{2}= 6.433\ atm

P_{2}=6.4\ atm

Hence, The pressure of the remaining gas in the tank is 6.4 atm.
