Answer:
<em>The final volume of methane gas = 2.5 L</em>
Explanation:
Charles' Law: Charles' law states that the volume of a given mass of gas is directly proportional to it's absolute temperature provided the pressure remains constant.
From Charles' law
V₁/T₁ = V₂/T₂
Making V₂ The subject of the equation above,
V₂ = (V₁/T₁)T₂........................... equation 1
Where V₁ = initial Volume, T₁ Initial Temperature, V₂ = Final Volume, T₂ = final Temperature.
<em>Given: V₁ = 5.00 L, T₁ = 298 K, T₂ = 148 K</em>
<em>Substituting these values into equation 1</em>
<em>V₂ = (5.00/298)149</em>
<em>V₂ = 2.5 L.</em>
<em>Therefore the final volume of methane gas = 2.5 L</em>
A) one ... same current passes through each cpt
Answer:
Part A: 16.1 V
Part B: 20.5 V
Part C: 21.5%
Explanation:
The voltmeter is in parallel with the 4.5-kΩ resistor and the combination is in series with the 6.5-kΩ resistor. The equivalent resistance of the parallel combination is given as
Part A
The voltmeter reading is the potential difference across the parallel combination. This is found by using the voltage-divider rule.
Part B
Without the voltmeter, the potential difference across the 4.5-kΩ resistor is found using the same rule as above:
Part C
The error in % is given by
1 kg = 1,000 grams
To get 75kg in units of grams, we just multiply 75 by 1,000
75* 1,000 = 75,000 grams
