Given what we know, we can confirm that since Mr. Summers has to test a hypothesis, his next step should be to design an experiment.
<h3>Why design an Experiment?</h3>
- The next step is to design an experiment.
- This is because Mr. Summers has already made an observation and created a problem.
- He must now gather data to be analyzed.
- In order to do this, he must first design and perform an experiment.
Therefore, we can confirm that Mr. Summers must design an experiment given that this is the best way to gather data in order to be analyzed in the future and draw a valid conclusion.

The granite loses 1.53 × 10⁸ J of heat.
The formula for the heat (<em>q</em>) transferred is
<em>q = mC</em>Δ<em>T
</em>
I shall assume that the specific heat capacity of granite is 0.790 J·°C⁻¹g⁻¹.
<em>m</em> = 3.580 × 10⁶ g; Δ<em>T</em> = <em>T</em>_f – <em>T</em>_i = -12.9 °C - 41.2 °C = -54.1 °C
∴ <em>q</em> = 3.580 × 10⁶ g × 0.790 J·°C⁻¹g⁻¹ × (-54.1 °C) = -1.53 × 10⁸ J
The granite block loses 1.53 × 10⁸ J.
The answer is the carbon cycle
These waxes are highly hydrophobic (repellant) of water, so the correct answer would be D) repel.
The wax coating put on the car creates a water repellant sheila that causes the water to bead up on the surface of the wax, rather than directly impacting the paint and surface of the body of the car. This prolongs the life and quality of the appearance of the car.
