    • B.

      Pascals,Joules,Newtons

    • C.

      Joules,Pascals,Newtons

    • D.

      Ml,g,ml squared.

    • E.

      None of the above

    Correct Answer
    B. Pascals,Joules,Newtons
    Explanation
    Pressure is measured in Pascals because Pascal is the SI unit of pressure. Work is measured in Joules because Joule is the SI unit of work and energy. Force is measured in Newtons because Newton is the SI unit of force.

    When air is released in a submarine it is able to dive.This process enable the sumbarine to

    • A.

      Decrease the viscosity

    • B.

      Decrease its pressure

    • C.

      Increase its buoyancy

    • D.

      Increase its density

    • E.

      Decrease its pressure

    Correct Answer
    D. Increase its density
    Explanation
    When air is released in a submarine, it increases its density. This is because the air takes up space and displaces water, causing the overall density of the submarine to increase. As a result, the submarine becomes heavier and sinks deeper into the water, enabling it to dive.

  • 3. 

    Condensation is The state in which a _______ goes to a _____

    • A.

      Gas to Solid

    • B.

      Liquid to Solid

    • C.

      Liquid to Gas

    • D.

      Solid to Gas

    • E.

      Gas to Liquid

    Correct Answer
    E. Gas to Liquid
    Explanation
    Condensation is the process in which a gas changes into a liquid. This occurs when the gas loses heat energy and its particles slow down, coming together to form a liquid. This can be observed, for example, when water vapor in the air cools and turns into liquid water droplets, forming clouds or dew.

  • 4. 

    When you measure how thick or thin something is your measure how _____it is,

    • A.

      Viscouse

    • B.

      Dense

    • C.

      Buoyant

    • D.

      None of the above

    Correct Answer
    A. Viscouse
    Explanation
    When you measure how thick or thin something is, you are measuring how viscous it is. Viscosity refers to the resistance of a fluid to flow, and a high viscosity indicates that the fluid is thick or sticky, while a low viscosity indicates that the fluid is thin or runny. Therefore, the correct answer is "Viscous."

    What is a solution?

    • A.

      When a solute dissolves in a solvent

    • B.

      When a colloid dissolves in a solvent

    • C.

      When a Solvent dissolves a solute

    • D.

      When a colloid dissolves in a solute

    • E.

      All the above

    Correct Answer
    A. When a solute dissolves in a solvent
    Explanation
    A solution is formed when a solute dissolves in a solvent. In a solution, the solute particles are dispersed and evenly distributed throughout the solvent, resulting in a homogeneous mixture. This is the most common and basic definition of a solution.

    Rate this question:

  • 6. 

    Fluid A has a flow rate of 9.2ml, per second, Fluid B has a flow rate of 10.5ml, per second. Compared to Fluid A, fluid B is...

    • A.

      The same

    • B.

      More Dense

    • C.

      More viscouse

    • D.

      Less Dense

    • E.

      Less Viscouse

    Correct Answer
    E. Less Viscouse
    Explanation
    Fluid B is less viscous compared to Fluid A because viscosity is a measure of a fluid's resistance to flow. A lower viscosity means that the fluid flows more easily, while a higher viscosity indicates a thicker, more resistant flow. Since Fluid B has a higher flow rate than Fluid A, it implies that Fluid B flows more easily and therefore has a lower viscosity.

    All of the following are ways to increase Rate of Dissolving, exept...

    • A.

      Aggitation

    • B.

      Increase tempreture

    • C.

      Saturation

    • D.

      Decrease tempreture

    • E.

      Surface area

    Correct Answer
    D. Decrease tempreture
    Explanation
    Decreasing temperature does not increase the rate of dissolving. When the temperature is decreased, the kinetic energy of the solvent particles decreases, resulting in slower movement and fewer collisions with the solute particles. This leads to a slower dissolution process and a lower rate of dissolving. On the other hand, agitation, increasing temperature, and increasing surface area all contribute to an increase in the rate of dissolving. Agitation helps in mixing the solvent and solute particles, increasing temperature increases the kinetic energy and collision frequency, and increasing surface area provides more contact points for the solute particles to interact with the solvent.

    If it takes 60 seconds for 12 ml of dirty oil to flow out of an engie, the flow rate is....

    • A.

      0.2

    • B.

      20

    • C.

      5

    • D.

      0.5

    • E.

      720

    Correct Answer
    A. 0.2
    Explanation
    The flow rate can be calculated by dividing the volume of oil (12 ml) by the time taken (60 seconds). Therefore, the flow rate is 0.2 ml/second.

    The reason rocks feel heavier in water than in air is beacuse of...

    • A.

      Buoyant force of rock

    • B.

      Buoyant force of water

    • C.

      Densirty of water

    • D.

      Mass of rock and water together

    • E.

      None of the above

    Correct Answer
    B. Buoyant force of water
    Explanation
    Rocks feel heavier in water than in air because of the buoyant force of water. When an object is submerged in a fluid, it experiences an upward force called buoyancy. This force is equal to the weight of the fluid displaced by the object. Since water is denser than air, it exerts a greater buoyant force on the rock, making it feel heavier. The buoyant force counteracts the force of gravity, resulting in the perception of increased weight when submerged in water.
