4.) True:
Since
P(E) = 1 - P(Ec)
P(E)+P(Ec)=1
If you think of it as the chances of you getting e or not getting e, then it's a 100% chance of either one happening.
Answer:
C = 0.5621J/g°C
Explanation:
Heat lost by metal = Heat gained by water
Heat gained by water;
H = MC ΔT
ΔT = 28 -25 = 3.0°C
M = 130.0g
C = 4.18 J/g°C
H = 130 * 4.18 * 3 = 1639J
Heat lost my metal;
H = MCΔT
ΔT = 100 - 28 = 72°C
M = 40.5g
C = ?
C = H / MΔT
C = 1639 / (40.5 * 72)
C = 0.5621J/g°C
