How many cycles happen in a given unit of time is called a wave's frequency.
Answer:
Q = 6688 J
Explanation:
Given data:
Energy absorbed = ?
Mass of water = 80 g
Initial temperature = 40°C
Final temperature = 60°C
Solution:
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
specific heat capacity of water 4.18 j/g.°C
ΔT = 60°C - 40°C
ΔT = 20°C
Q = 80 g ×4.18 j/g.°C × 20°C
Q = 6688 J
It’s definitely B but I’m not sure
Answer:
2.06 atm
Explanation:
The computation of the pressure inside the flask is shown below;
As per the ideal gas law
we know that
P V = nRT
where
V = 1.50L
T = 325 K
R = 0.0821
Now moles of N_2 is
= 3.25 ÷ 28
= 0.116 mol
Now
P = NRT ÷ V
= 0.116 × 0.0821 × 325 ÷ 1.50
= 2.06 atm
