66 A student wants to design a controlled experiment to solve the following problem: When placed in a freezer, will hot water or cold water reach 0°C faster? The student plans to place two containers with equal masses of water (one hot and one cold) in the same freezer in the classroom.
a List three conditions the student should keep constant for the hot-water and cold-water setups when planning this experiment. [3]
b For each condition you name, give a scientific reason why the condition needs to be the same for both the hot-water and cold-water setups

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
