The independent variable in this question is the angle of light. It is the variable that is being changed or manipulated to observe its effect on the temperature of the surface.
The independent variable when building a raft powered by surface tension would be the raft design or materials used. By changing these factors, you can observe how they affect the ability of the raft to float and move on the water surface due to surface tension.
An increase in temperature typically decreases surface tension in liquids. This is because higher temperature leads to increased molecular motion, which weakens the intermolecular forces responsible for surface tension.
Different aspects of temperature that can be measured include ambient temperature (air temperature in the surrounding environment), surface temperature (temperature of an object's surface), body temperature (temperature of a living organism), and water temperature (temperature of water in a body of water).
If you decrease a planet's orbital radius, its surface temperature will increase.
True. When evaporating a liquid, heat is added to increase its temperature until it reaches its boiling point. At this temperature, the liquid changes to bubbles of gas below its surface, transitioning from a liquid to a gas phase.
That the surface tension of water varies with the water's temperature. In this case, temperature would be the independent variable and surface tension would be the independent variable.
Temperature.
The independent variable in an experiment involving Alka-Seltzer could be the amount of Alka-Seltzer used, the temperature of the water it's dissolved in, or the surface area of the Alka-Seltzer tablet. It is the variable that is deliberately changed or manipulated by the experimenter to observe its effect on the dependent variable.
Yes The independent variable is also known as the manipulated variable. In an experiment where you need to test different objects, the independent variable would be the different objects.
The independent variable in the Magnesium Oxide Lab would be the Mass of the Magnesium Ribbon. This is because the mass of the product, i.e. Magnesium Oxide, depends on how much Magnesium is added.
The temperature and the amount of water need to be kept the same so that the only variable that changes is surface area. If you allow the temperature and/or the amount of water to change too, you will not know which variable is causing the changes that you observe.
In this scenario, the independent variable is the person's running speed, as it can be manipulated to observe its effect on the dependent variable. The dependent variable is the time it takes to run a mile, as it changes in response to the running speed. There may also be constant variables, such as the distance of one mile and environmental conditions (e.g., track surface, weather) that remain unchanged during the experiment.

Rigel is a blue-white supergiant star with a surface temperature of around 11,000 Kelvin. Its color appears blue to the human eye due to its high temperature, and its surface is turbulent and variable, with strong stellar winds and intense radiation.
The independent variable when building a raft powered by surface tension would be the raft design or materials used. By changing these factors, you can observe how they affect the ability of the raft to float and move on the water surface due to surface tension.
The temperature layers in ocean water are typically divided into three main zones: the surface zone, the thermocline, and the deep zone. The surface zone is the warmest and most variable in temperature due to interaction with the atmosphere. Below the surface zone is the thermocline, where temperature decreases rapidly with depth. Finally, the deep zone is characterized by consistently cold temperatures.
The surface temperature of a star is indicated by its color or spectral type. Blue stars have higher surface temperatures compared to red stars. By analyzing the star's color and spectrum, astronomers can determine its surface temperature.
