What else can I help you with?
The rate of heat loss from the hot cup change during the experiment answer?
The rate of heat loss from the hot cup decreased during the experiment.
List some variables that can change in an experiment and discuss the importance of a control group?
list some variables that can change in an experiment?
What is the difference between a constant and a control group?
The constant is the base example that does not have any type of manipulation done to it. the control group would be the example that is manipulated in the same way that the other groups in the experiment are but without the addition of any of the reactants. Imagine your experiment was seeing the results of water boiling times. your constant would be the pot of water at room temperature without heat, the control group would be the pot that is placed on the stove being heated, and the Experimental group would be the one that you add salt to. (the variable that is being tested)
When would you cool a casualty's body by sprinkling water during a heat emergency?
heat exhaustion
How do containers effect temperature of water?
It depends on what the container is made of. Say it was made of tin and was a hot day, the water would become hot because the tin would heat up and the water would steal the heat energy because it is cooler.
Which holds more heat salt water or fresh water?
Salt water holds more heat than fresh water
What holds heat longer soil or water?
Water holds heat longer than soil. This is because water has a higher specific heat capacity than soil, meaning it requires more energy to heat up or cool down compared to soil. As a result, water can store more thermal energy and retain heat for a longer period of time.
Does soil or water heat hold heat more effectively?
Electricity holds the most heats
What holds heat longer salt water or fresh water?
Salt Water, do to its small salt particles which not only the water holds the heat ,but the salt particles TOO!!! Most brines for heat transfer systems are very heavily salted solutions to the point where there is more salt than water [by weight] in them.
How would you separate sugar and water in an experiment?
You could heat the water until it evaporates and condense the vapours to water. However, you would have to be extremely careful to ensure that none of the remaining sugar was caramelised (burnt).
Which holds heat longer land or water?
Water holds heat longer than land because of its higher specific heat capacity. This means that water can absorb and retain more heat compared to land, resulting in a slower rate of temperature change. This property is why coastal areas have milder climates than inland regions.
What effect does heat have on an experimental plant?
In general, heat waves do not have any effect on the biomass of a plant in an experiment. The heated water or water from a microwave also does not affect the plant.
Does water or land hold heat longer?
Water holds heat longer than land because it has a higher specific heat capacity, meaning it takes more energy to raise its temperature. As a result, water can absorb and retain heat more effectively than land. This is why coastal areas tend to have milder temperatures compared to inland areas, as water moderates the climate by releasing heat slowly.
What holds more heat wet soil or dry soil and why?
Dry soil holds more heat than wet soil because water has a high heat capacity, which means it takes more energy to heat up water compared to soil. When soil is wet, a portion of the incoming heat energy is used to evaporate the water, thereby reducing the overall heat absorbed by the soil.
Why should you stir the water at the end of the experiment specific heat capacity?
Stirring the water at the end of the experiment helps ensure that the temperature throughout the water is uniform, which is important for accurate measurements of specific heat capacity. It helps to distribute the heat evenly and eliminate any temperature gradients that may affect the results.
Is magma waterproof?
yes because the molten rock is heavy so the water floats on top of it like the oil and water experiment but even so, the heat of the magma would turn the water to steam faster than you can say two.
What is a dependnent variable?
A dependent variable depends on the independent variable. If you are doing an experiment about how temperature affects the heat of water then the independent variable would be the temperature, as that is what you are going to change, and the dependent variable the water as the temperature of the water depends on the temperature surrounding it.
