<h2>
The asteroid is 4.11 x 10¹¹ m far from Sun</h2>
Explanation:
We have gravitational force
Where G = 6.67 x 10⁻¹¹ N m²/kg²
M = Mass of body 1
M = Mass of body 2
r = Distance between them
Here we have
M = Mass of Sun = 1.99×10³⁰ kg
m = Mass of asteroid = 4.00×10¹⁶ kg
F = 3.14×10¹³ N
Substituting
The asteroid is 4.11 x 10¹¹ m far from Sun
temperature rises ? specific heat capacity etc ...
Since the outer plumage of the penguin can resist the flow of heat in the cold antarctic air they might gain a little of this heat to keep them warm by thermal convection.
<u>Explanation:</u>
- Convection is the circular movement that happens when hot air/liquid moves with molecules that were fast, making it less dense rises while the cold air/liquid drops down.
- Also, they follow the technique of standing together always in a group which further helps them to decrease the loss of heat between them.
- The plumage of penguin provides 80 percent of total insulation and is highly resistant to wind penetration.
Answer:
Explanation:
- The concept of gibb's free energy is applied in the problem. Mathematically from Gibb's free energy ; ΔG = ΔH - TΔS
- Entropy = ΔS = is the degree of disorderliness of the system.
- Since the enthalpy of vaporization is given ΔHvap = 38.0kJ/mol = 38000J/mol
- Also ΔSvap = 112.9J/mol.K
- Temperature of the experiment given = 75 degree celsius
calculate the boiling point of the solvent ; T = ΔHvap/ΔSvap
- T = 38000J/mol / 112.9J/mol.K
- = 335.57K , in celsius ; 335.57K - 273
the temperature calculated indicates that the solvent is not suitable for the experiment because its boiling point is lesser than the temperature at which the experiment want to be carried out.
