Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
1) nuclear fusion
During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. During this process, radiant energy is released.
Answer:
T₂ =602 °C
Explanation:
Given that
T₁ = 227°C =227+273 K
T₁ =500 k
Gauge pressure at condition 1 given = 100 KPa
The absolute pressure at condition 1 will be
P₁ = 100 + 100 KPa
P₁ =200 KPa
Gauge pressure at condition 2 given = 250 KPa
The absolute pressure at condition 2 will be
P₂ = 250 + 100 KPa
P₂ =350 KPa
The temperature at condition 2 = T₂
We know that
![\dfrac{T_2}{T_1}=\dfrac{P_2}{P_1}\\T_2=T_1\times \dfrac{P_2}{P_1}\\T_2=500\times \dfrac{350}{200}\ K\\](https://tex.z-dn.net/?f=%5Cdfrac%7BT_2%7D%7BT_1%7D%3D%5Cdfrac%7BP_2%7D%7BP_1%7D%5C%5CT_2%3DT_1%5Ctimes%20%5Cdfrac%7BP_2%7D%7BP_1%7D%5C%5CT_2%3D500%5Ctimes%20%5Cdfrac%7B350%7D%7B200%7D%5C%20K%5C%5C)
T₂ = 875 K
T₂ =875- 273 °C
T₂ =602 °C
energy never disappears, for example, if you give some kinetic energy to a ball and it stops few seconds later, friction steals this energy to ground which ball was going on. "Law of Conservation of Energy" tell us that energy can't disappear
