Answer:
108.37°C
Explanation:
P₁ = Initial pressure = 101 kPa
V₁ = Initial volume = 530 m³
T₁ = Initial temperature = 10°C = 10+273.15 =283.15 K
P₂ = Final pressure = 101 kPa (because it is open to atmosphere)
V₂ = Final volume = 530 m³
P₁V₁ = n₁RT₁
⇒101×530 = n₁RT₁
⇒53530 J = n₁RT₁
P₂V₂ = n₂RT₂
⇒53530 J = n₂RT₂
Dividing the first two equations we get
∴Temperature must the air in the balloon be warmed before the balloon will lift off is 381.25-273.15 = 108.37°C
Answer:
1) Lithospheric plates move in the asthenosphere due to rising and sinking of materials is 1.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core
5) The process repeats as cycle.
Explanation:
Mantle convection is the gradual slow creeping of movement of the Earth's mantle which is as a result of convection current which transfer heat from the interior to the surface of the Earth .
The process of mantle convection start with
1. Lithospheric plates move in the asthenosphere due to rising and sinking of materials is and thus form the two component of the mantle.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth. This is as a result of accretion which is associated to sea flooding
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core, cools down by conduction and convection of heat.
5) The process repeats as cycle.
