NEET Physics: Thermal Properties of Matter — MCQ Test 9

Q6. Why does steam at \( 100^\circ \text{C} \) cause more severe burns than water at \( 100^\circ \text{C} \)?

Q7. How much heat is required to convert \( 0.25 \, \text{kg} \) of ice at \( -15^\circ \text{C} \) to water at \( 60^\circ \text{C} \) in a \( 0.15 \, \text{kg} \) iron calorimeter initially at \( 20^\circ \text{C} \)? (Specific heat of ice = \( 2100 \, \text{J kg}^{-1} \text{K}^{-1} \), latent heat of fusion = \( 3.35 \times 10^5 \, \text{J kg}^{-1} \), specific heat of water = \( 4186 \, \text{J kg}^{-1} \text{K}^{-1} \), iron = \( 450 \, \text{J kg}^{-1} \text{K}^{-1} \))

Q8. A gas at \( 67^\circ \text{C} \) and \( 1.6 \, \text{atm} \) occupies \( 8 \, \text{L} \). If the temperature is reduced to \( 17^\circ \text{C} \) and volume adjusted to \( 6 \, \text{L} \), what is the final pressure?

Q9. What process occurs when dry ice changes directly from solid to vapor?

Q10. A gas at \( 2 \, \text{atm} \) and \( 47^\circ \text{C} \) occupies \( 6 \, \text{L} \). If the temperature drops to \( -3^\circ \text{C} \) and pressure becomes \( 1.5 \, \text{atm} \), what is the new volume?
