Answer:
Instead of normal protium atoms, heavy water consists of two deuterium atoms. Like normal water, heavy water is an odorless liquid at room temperature. Moreover, deuterium, tantamount to protium, is also a stable isotope. This ensures that heavy water is not radioactive
Answer:
The 150 g Al will reach a higher temperature.
Explanation:
- The amount of heat added to a substance (Q) can be calculated from the relation:
<em>Q = m.c.ΔT.</em>
where, Q is the amount of heat added,
m is the mass of the substance,
c is the specific heat of the substance,
ΔT is the temperature difference (final T - initial T).
Since, Q and c is constant, ΔT will depend only on the mass of the substance (m).
∵ ΔT is inversely proportional to the mass of the substance.
<em>∴ The piece with the lowest mass (150.0 g) will reach a higher temperature than that of a higher mass (250.0 g).</em>
<em>So, the right choice is: The 150 g Al will reach a higher temperature.</em>
Osmosis is about the movement of water molecules and diffusion is about the movement of substances
