Answer:
27 °C
Explanation:
Applying,
V/T = V'/T'................. Equation 2
Where V = Initial volume of oxygen, T = Initial temperature, V' = Final volume of oxygen, T' = Final temperature.
Make T' the subject of the equation
T' = V'T/V................ Equation 2
Form the question,
Given: V' = 600 mL, V = 460 mL, T = -43°C = (-43+273) = 230K
Substitute these values into equation 2
T' = (600×230)/460
T' = 300 K
T' = (300-273) °C
T' = 27 °C
Activation energy is a thermodynamic barrier that must be overcome before products are formed in a reaction. It is the minimum amount of energy needed for a reaction to occur. The energy can be in the form of kinetic or potential energy. This concept was introduced by Svante Arrhenius, which brought about the Arrhenius equation which is a formula used to determine rate of reactions.
The sun's rays hit the Earth at a extreme angle, which causes the days to become shorter, so yes, the sun's rays do hit the Earth at a extreme angle.
With a process called Fission. This generates heat to produce steam.
