In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits<span> into smaller parts (lighter </span>nuclei<span>). Hope this helps</span>

An iron ball is dropped onto a pavement from a height H. If half of the heat generated goes into warming the ball, find the temp

mr Goodwill [35]

The given question is incomplete. The complete question is as follows.

A 10 kg iron ball is dropped onto a pavement from a height of 100 m. If half of the heat generated goes into warming the ball,find the temperature increase of the ball. (In Sl units, the specific heat capacity of iron is 450 J/kg.C degree).

Explanation:

In the given case, when the ball comes in contact with the pavement then its kinetic energy will be equal to potential energy of the ball before it was dropped. Half the K.E heats the ball.

As K.E = P.E = mgh

So, mgh = $10 \times 10 \times 100$ = 10,000 joules

And, half of this is 5,000 joules

As we know that

Q = $m \times C \Delta T$

5000 = $450 \times 10 \times \Delta T$

$\Delta T = \frac{5000}{4500}$

= 1.11 degrees

Also, in the given situation

$\frac{mgh}{2} = m \times C \times \Delta T$

Since there is an m on both sides of the equation, we will divide both sides by m and the resulting equation will be as follows.

$\frac{gh}{2} = c \times \Delta t$

As, the result is independent of mass which is why the result is the same for any ball of any mass.

vodka [1.7K]

Answer:

P₂ = 1102 Kpa

Explanation:

Given data:

Initial pressure = 1000.0 Kpa

Initial temperature = 20.0°C

Final temperature = 50.0°C

Final pressure = ?

Solution:

Initial temperature = 20.0°C (20+273 = 293 K)

Final temperature = 50.0°C (50+273 = 323 K)

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1000 Kpa / 293 K = P₂/323 K

P₂ = 1000 Kpa × 323 K / 293 K

P₂ = 323000 Kpa. K /293 K

P₂ = 1102 Kpa
