  2. According to the kinetic theory of gases, at absolute zero (0 Kelvin or -273.15°C), the molecules of a substance have no kinetic energy and their motion theoretically stops completely. This is the lowest possible temperature. Click this more information: https://www.tiwariacademy.com/ncert-solutionsRead more

  3. Mercury thermometers can measure temperatures up to around 360°C because mercury stays in its liquid state up to this temperature. Beyond this, mercury begins to vaporize and cannot be used for measurements above this point. Click for more: https://www.tiwariacademy.com/ncert-solutions/class-11/physRead more

  4. The amount of sun's radiant energy received is proportional to the power output of the sun from Stefan-Boltzmann's Law: P ∝ R²T⁴ 1. Preliminary P₁ ∝ R²T⁴ 2. After alteration - The radius increases to 2R: The area increases proportionally to (2R)² = 4R² - Temperature increases to 2T: Power increasesRead more

    The amount of sun’s radiant energy received is proportional to the power output of the sun from Stefan-Boltzmann’s Law:
    P ∝ R²T⁴

    1. Preliminary
    P₁ ∝ R²T⁴

    2. After alteration
    – The radius increases to 2R: The area increases proportionally to (2R)² = 4R²
    – Temperature increases to 2T: Power increases proportionally to (2T)⁴ = 16T⁴
    – Total power increases to:
    P₂ ∝ 4R² × 16T⁴ = 64R²T⁴

    3. The ratio of the new power to the old power:
    P₂ / P₁ = (64R²T⁴) / (R²T⁴) = 64

    Thus, the radiant energy received on Earth will increase by a factor of 64.

    I enjoyed the hands-on experience of planting seeds, nurturing them with care, and witnessing their growth. Watering the plants and maintaining the garden offered a sense of responsibility and satisfaction. The highlight was harvesting fresh produce, which was a rewarding outcome of the effort. Additionally, designing the garden layout, arranging pots, and adding decorative elements enhanced the joy of the activity, making it both educational and creatively fulfilling.
