Alfisols can be found in humid areas and semiarid areas. They are formed in forest and savanna vegetation. They are very fertile and productive soils. These soils contains high concentrations of nutrient that are cations like calcium, magnesium, potassium and sodium.
Answer:
338 K
Explanation:
= 2.5 kg, c = 4189 J/(kg K), 
= 13.5 
, 
= 22.5
= 0.5 kg, 
= 20
Heat loss by hotter water = heat gained by cooler water
cΔT = cΔT
c( - ) = c(
- )
2.5 x 4189 x (22.5 - 13.5) = 0.5 x 4189 x ( - 20)
2.5 x 4189 x 9 = 2094.5 ( - 20)
94252.5 = 2094.5 - 41890
94252.5 + 41890 = 2094.5
136142.5 = 2094.5
= 
= 65
= 65
But,
θ K = 273 + θ
= 273 + 65
= 338
The final temperature of the water is 338 K.
Because they have added another solution, it means that the mixture was not yet saturated, so the correct answer is unsaturated, D
They describe a constant rate of acceleration. As in they don't increase at all they stay at a constant rate. The car though stopped because of a stop sign.
