Case Study Questions on Thermal Properties of Matter

Case Study Question 1

Thermal Expansion in Railway Tracks

Passage:
During summer, railway tracks expand due to heat. To prevent bending or buckling, small gaps are left between tracks. This phenomenon is due to linear thermal expansion governed by the formula:

$$
\Delta L=\alpha L \Delta T
$$

Where:
– $\Delta L=$ increase in length
– $\alpha=$ coefficient of linear expansion
– $L=$ original length
– $\Delta T=$ temperature change

Q1. A steel rail of length 10 m expands by how much if temperature rises by $40^{\circ} \mathrm{C}$ ? (Given $\alpha=1.2 \times$ $10^{-5} /{ }^{\circ} \mathrm{C}$ )
(a) 0.0048 m
(b) 0.048 m
(c) 0.012 m
(d) 0.024 m

Answer: (a)
Explanation:

$$
\Delta L=\alpha L \Delta T=1.2 \times 10^{-5} \times 10 \times 40=0.0048 \mathrm{~m}
$$

Q2. Which property of matter causes railway tracks to expand on heating?
(a) Conductivity
(b) Elasticity
(c) Thermal expansion
(d) Specific heat

Answer: (c)
Explanation:
Thermal expansion causes materials to increase in size when heated.

Q3. What would happen if no gaps were provided between tracks?
(a) Tracks would cool faster
(b) Tracks would contract
(c) Tracks may bend or buckle
(d) Nothing would happen

Answer: (c)
Explanation:
Without gaps, expansion due to heat causes internal stress, leading to bending or buckling.

Q4. Which material has the highest coefficient of linear expansion?
(a) Steel
(b) Brass
(c) Copper
(d) Invar

Answer: (b)
Explanation:
Among metals, brass has a higher expansion coefficient than steel or copper. Invar has extremely low expansion.

Case Study Question 2

Passage:
On a cold morning, if you touch a metal spoon and a wooden spoon, the metal spoon feels colder — even if both are at the same temperature. This observation is often misunderstood unless one understands thermal conductivity.

Q1. Why does the metal spoon feel colder than the wooden one?
(a) Metal is colder by nature
(b) Wood generates heat
(c) Metal conducts heat away from your hand faster
(d) Wood is denser

Answer: (c)
Explanation:
Metal has higher thermal conductivity, so it pulls heat from your hand quickly, making it feel colder.

Q2. What property of material governs how fast it draws heat from your hand?
(a) Specific heat
(b) Density
(c) Thermal conductivity
(d) Elasticity

Answer: (c)
Explanation:
Thermal conductivity controls how fast heat is transferred.

Q3. What would happen if both spoons were at room temperature?
(a) Metal still feels colder
(b) Wood feels colder
(c) Both feel equally cold
(d) Depends on humidity

Answer: (a)
Explanation:
Even at same temperature, the rate of heat transfer from hand to material affects our perception.

Q4. Which of the following materials would feel the warmest at same temperature?
(a) Iron
(b) Copper
(c) Glass
(d) Wool

Answer: (d)
Explanation:
Wool is a poor conductor → absorbs less heat from your skin → feels warm
