For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

How many Joules are released to cool 250.0 grams of liquid water from 100°C to 0°C? The specific heat of water is 4.180 J/g.C.

nlexa [21]

$\bold{\huge{\orange{\underline{ Solution}}}}$

$\bold{\underline{ Given :- }}$

We have 250g of liquid water and it needs to be cool at temperature from 100° C to 0° C
Specific heat of water is 4.180J/g°C

$\bold{\underline{ To \: Find :- }}$

We have to find the total number of joules released.

$\bold{\underline{ Let's \:Begin:- }}$

We know that,

Amount of heat energy = mass * specific heat * change in temperature

That is, 

$\sf{\red{ Q = mcΔT }}$

Subsitute the required values in the above formula :-

$\sf{ Q = 250 × 4.180 ×(0 - 100 )}$

$\sf{ Q = 250 × 4.180 × - 100 }$

$\sf{ Q = 250 × - 418}$

$\sf{\pink{ Q = - 104,500 J }}$

Hence, 104,500 J of heat is released to cool 250 grams of liquid water from 100° C to 0° C.

$\bold{\underline{ Now :- }}$

We have to tell whether the above process is endothermic or exothermic :-

Here, In the above process ΔT is negative and as a result of it Q is also negative that means above process is Exothermic

Exothermic process :- It is the process in which heat is evolved .
Endothermic process :- It is the process in which heat is absorbed .

How does renewable energy differ from nonrenewable energy? 5-6 paragragh

levacccp [35]

Resources are categorized as renewable or non-renewable. A renewable resource may replenish at the rate it is being used, while a non-renewable resource has a limited supply.

Explanation:

Renewable Energy:

It is the energy that is obtained from natural resources like sun, wind, etc..
It is the cleanest form of energy.
15% of the world's total energy depends upon renewable energy.

Advantages of renewable energy:

Renewable energy is free to use and it is available in the abundant quantity.
They produce low carbon emissions and it does not affect the environment.

Dis-Advantages of renewable energy:

The initial step cost much like setting up the windmill and solar panels to obtain energy.
Solar energy needs backup during the winter season.

Non-Renewable Energy

A natural resource or source of energy existing finite quantity and not capable of being replenished.
They are not environmentally friendly and it leads to environmental issues.

Advantages of Non-Renewable Sources:

The Non-Renewable Sources is considered as cheap to use.
They produce a tremendous amount of energy

Disadvantages of Non-Renewable Sources:

Non-renewable sources release toxic gases in the air when burnt which are the major cause of global warming.
