What is the direction of the movement of the food coloring when mixed with water?
In hot water, the food coloring diffuses (spreads out) through the water quickly. In cold water, the food coloring diffuses (spreads out) through the water slowly. The hot water causes the food coloring to diffuse faster. At higher temperatures, particles move faster.
How does the color of water affect the time it takes to freeze?
Salt lowers the freezing point of water. Food coloring has no effect on the freezing temperature of water, so it will freeze at the same temperature as the plain water.
What have you observed is there water left in the plastic why Brainly?
Yes, theres water left in the plastic because when I pour it some of water didn’t fell.
What have you observed about the objectives?
Explanation: The objective is the vital part of the microscope that is just above the specimen and provides an “intermediate image of the specimen” and is responsible for the “primary image formation” and “image magnification”.
What happened to the plastic bag as the air inside is warmed Brainly?
The plastic bag will explode because it is hot inside it because the candle heat outside the plastic bag.
What are the properties of liquid Brainly?
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.
What are the properties of liquids?
All liquids show the following characteristics:
- Liquids are almost incompressible. In liquids molecules are pretty close to each other.
- Liquids have fixed volume but no fixed shape.
- Liquids flow from higher to lower level.
- Liquids have their boiling points above room temperature, under normal conditions.
What is the importance of properties of liquid Brainly?
Answer: The most obvious physical properties of a liquid are its retention of volume and its conformation to the shape of its container. When a liquid substance is poured into a vessel, it takes the shape of the vessel, and, as long as the substance stays in the liquid state, it will remain inside the vessel.
What happens when balloon is cooled?
By the low temperature the pressure of the gas inside the balloon tends to decrease. When the balloon is cooled, the volume of the balloon is greater, resulting in a greater average density of the balloon and helium. This makes the balloon come down.
Why does a balloon burst when we try to squeeze it?
The air in a balloon is at a higher pressure than its surroundings because the elastic tension of the balloon skin is pulling inwards. The high-pressure air that was inside the balloon is now free to expand and this creates a pressure wave that our ears hear as a bang.
