Reil [10]

Answer:

2.13\%

Explanation:

Quantity of copper measured by a student = 4.6 grams

Original quantity of copper = 4.7 grams

Error in measurement = Original quantity of copper - Quantity of copper measured by a student  =4.7-4.6=0.1 grams

To find the percent error, apply the following formula:

Percent error = (Error in measurement / Original quantity of copper) × 100

=\frac{0.1}{4.7}(100)=2.13\%

worty [1.4K]

The final temperature :T₂=411.125 K = 138.125 °C

<h3>Further explanation</h3>

Given

T₁=-20 °C+273 = 253 K

V₁=40 ml

V₂=65 ml

Required

Final temperature

Solution

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

Input the value :

T₂=(V₂.T₁)/V₁

T₂=(65.253)/40

T₂=411.125 K = 138.125 °C
