Answer:
Chemical weathering due to water
Explanation:
Since all the water is pulled underground through cracks and crevices on the surface, it makes the limestone plateau have no surface water. Meanig the most likely cause for having the underground of the plateau to change over time is the chemical weathering due to water.
This is true they are defined as protons
Answer:
c =0.2 J/g.°C
Explanation:
Given data:
Specific heat of material = ?
Mass of sample = 12 g
Heat absorbed = 48 J
Initial temperature = 20°C
Final temperature = 40°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 40°C -20°C
ΔT = 20°C
48 J = 12 g×c×20°C
48 J =240 g.°C×c
c = 48 J/240 g.°C
c =0.2 J/g.°C
1 significant figure, because there is no decimal after the zero the zero doesn't count.
