The temperature of a block of iron is 140°F. Its temperature on the Celsius scale is:
Detailed Solution for Test: Temperature & Its Measurement & Thermal Expansion (September 3) - Question 5
To convert Fahrenheit to Celsius, you can use the formula:

°C = (°F - 32) * 5/9

So, for 140°F:
°C = (140 - 32) * 5/9
°C ? 60°C

Therefore, the temperature on the Celsius scale is approximately 60°C. So, the correct answer is Option B.

A lemon when dropped into a large glass container containing ordinary tap water is found to sink to its bottom. Which of the following actions can be helpful in making this lemon float?
(A) Adding more water to the container.
(B) Adding salt to the water in the container.
Detailed Solution for Test: Temperature & Its Measurement & Thermal Expansion (September 3) - Question 6
Adding salt to the water in the container (option B) can be helpful in making the lemon float. The increased salt concentration increases the water's density, making it more buoyant and allowing the lemon to float. Adding more water (option A) would not change the water's density significantly. So, the correct answer is Option B.

A small aluminum rod 5 cm × 10 cm sinks when immersed in water taken in a container. Which of the following actions can be helpful in making this rod float?
(A) Adding more water to the container
(B) Reshaping the rod in the shape of a boat
Detailed Solution for Test: Temperature & Its Measurement & Thermal Expansion (September 3) - Question 9
Reshaping the rod in the shape of a boat (option B) can be helpful in making the small aluminum rod float. Changing the shape of the rod can displace more water, increasing buoyancy and allowing the rod to float. Adding more water (option A) would not change the rod's ability to float significantly. So, the correct answer is Option B.

Railway lines, 25 m long, are being laid when the temperature is 15°C. Gaps of 1.8 cm are being left between them. If ? = 12×10^-6/°C, the temperature at which they will touch each other is ______
Detailed Solution for Test: Temperature & Its Measurement & Thermal Expansion (September 3) - Question 10
To find the temperature at which the railway lines will touch each other, we can use the formula:

?T = (? * L * ?L) / (2 * L)

Where:
?T = Change in temperature
? = Coefficient of linear expansion
L = Original length of the railway lines
?L = Change in length (1.8 cm = 0.018 m)

?T = (12 × 10^-6/°C * 25 m * 0.018 m) / (2 * 25 m)
?T = 0.00027°C

The temperature change is 0.00027°C. To find the final temperature, we add this change to the initial temperature:

Final Temperature = Initial Temperature + ?T
Final Temperature = 15°C + 0.00027°C
Final Temperature ? 15.00027°C

So, the temperature at which the railway lines will touch each other is approximately 15.00027°C, which can be rounded to 15°C. Therefore, the correct answer is Option C.
