Answer:
Final volume after applying 880 mmHg pressure = 89.28
Explanation:
Initial volume (V 1)= 100 ml
Initial pressure (P1) =780 mm Hg = 780/780 = 1atm
Final pressure (P2)=880 mm Hg = 880/780 =1.12 atm
Final volume (V2)=?
We know that,
Applying Boyle's law,
P1 V1=P2 V2
1*100=1.12*V2
100=1.12*V2
100/1.12=V2
89.28=V2
V2=89.28 ml

Example 1: A 36.0 g sample of water is initially at 10.0 °C.
How much energy is required to turn it into steam at 200.0 °C? (This
example starts with a temperature change, then a phase change followed
by another temperature change.)
Solution:
<span>q = (36.0 g) (90.0 °C) (4.184 J g¯1 °C¯1) = 13,556 J = 13.556 kJ
q = (40.7 kJ/mol) (36.0 g / 18.0 g/mol) = 81.4 kJ
q = (36.0 g) (100.0 °C) (2.02 J g¯1 °C¯1) = 7272 J = 7.272 kJ
q = 102 kJ (rounded to the appropriate number of significant figures)

Answer:
The type of collision is A. Inelastic collision.
Explanation:
The macroscopic collisions are generally inelastic and do not conserve the kinetic energy, although of course the total energy is conserved. The inelastic collision is one in which the objects that collide remain together after the collision.
So, a figure skater skating across ice, who grabs another skater and brings him along the ice with her is a clear example of inelastic collision.
Answer:
49.54%
Explanation:
Given parameters:
Number of organisms in original habitat = 4695
Number of organism in new habitat = 2326
Solution:
To find the percentage of the organisms in the new habitat that has migrated to the new habitat, we use the expression below:
% of the population in the new habitat = x 100
% of the population in the new habitat = x 100 = 49.54%
