How are mixtures and solutions different?
1.Unlike a solution, a mixture has density and will always sink in a liquid because mixtures lack buoyancy.
2.Unlike a solution, a mixture can dissolve completely in a liquid because the properties of the ingredients change.
3.Unlike a solution, a mixture is unable to change states of matter from a solid to a liquid or gas.
4.Unlike a solution, a mixture can easily be separated and each ingredient keeps its physical properties.

How did this piece of evidence change your thinking about the channel on Mars? Explain your ideas below.
Answers
The piece of evidence changed thinking about the channel on Mars because it shows that the rock was formed next to flowing water as such rock formations exist on Earth and were formed by flowing water.
Was there flowing water on Mars ?The geologic process that could have created the channel on Mars is water moving. We can infer from the image that water running across the terrain on Mars created channels similar to those on Earth.
We can claim that the flowing of water creates the channels on Mars because when the water runs for a long period from the same region, it takes the sediments and creates channels.

Explanation:
When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as

Answer:
Dish C
Explanation:
In order to find which dish would make the food dish the hottest we need to find which dish out of the three options has the most enegrgy. We can find how much energy a dish has by couting the number for circles and multiplying it by the number inside the circles . For example, dish a has 11 cirlces and 30x11 is 330. Dish a has 330 unit of energy. If we repeat that process with the other two dishes we see that dish B has 110 units of energy and dish A has 350 units of energy. Since dish C has a larger amount of engery it willl make the food dish the warmest when stacked. The engery of the top dish, dish c, will flow down to the food dish in the form of heat. This process will then cointue warming the food dish and cooling dish C until they have thesame/similar levels of energy/temprature.
Which option is an example of a chemical property?
melting point
density
ability to decompose
color
Answers
The ability to decompose
Explanation:
A property is a chemical property when it changes the chemical structure of a substance after a reaction.
Density and color are both physical properties.
Even though melting point may seem like a chemical property, when something melts, only the physical state changes, and the chemical structure does not change, and therefore, is a physical property.
The ability to decompose is a chemical property. When something decomposes, the chemical structure of many molecules change, and therefore, is classified as a chemical property.
