The granite block transferred <u>4080 J</u> of energy, and the mass of the water is <u>35.8 g</u>.
1. <em>Energy from granite block
</em>
The formula for the heat (<em>q</em>) transferred is
<em>q = mC</em>Δ<em>T</em>
<em>m</em> = 126.1 g; <em>C</em> = 0.795 J·°C⁻¹g⁻¹; Δ<em>T</em> = <em>T</em>_f – <em>T</em>_i = 51.9 °C - 92.6 °C = -40.7 °C
∴ <em>q</em> = 126.1 g × 0.795 J·°C⁻¹g⁻¹ × (-40.7 °C) = -4080 J
The granite block transferred 4080 J.
2. <em>Mass of water
</em>
<em>q = mC</em>Δ<em>T
</em>
<em>m = q</em>/(<em>C</em>Δ<em>T</em>)
<em>q </em>= 4080 J; <em>C</em> = 4.186 J·°C⁻¹g⁻¹; Δ<em>T</em> = <em>T</em>_f – <em>T</em>_i = 51.9 °C – 24.7 °C = 27.2 °C
∴ <em>m</em> = 4080 J/(4.186 J·°C⁻¹g⁻¹ × 27.2 °C) = 35.8 g
The mass of the water is 35.8 g.

Living things are <u>interdependent </u>with each other and the environment.
Explanation:
Living things to grow, thrive, survive and reproduce are interdependent on each other and their surrounding environment. They depend on each other and the environment for basic requirements which support life like water, air, food etc.
The food cycle starting with the producers, consumers, decomposers and their interdependence with each other for energy production is a clear example for this. They are dependent on each other for reproduction and growth. They are dependent on the environment for living in their habitat and for raw materials for producing food.
The rate of formation of water and the decomposition of hydrogen peroxide is double as compared to rate of formation of oxygen.
<h3>What is chemical reaction?</h3>
The chemical reaction is given as the reaction of the reactants in the process to form the new compound.
The chemical reaction with the decomposition of hydrogen peroxide is:
The rate of formation of water is given to be double the rate of formation of oxygen as 2 moles of water formed with 1 mole of oxygen.
The rate of disappearance of hydrogen peroxide is double with formation of oxygen as for decomposition of 2 moles of hydrogen peroxide, 1 mole of oxygen is formed.
