A liquid in a beaker is heated. For the liquid at the bottom of the beaker, state, what happens to its mass, volume and density
Answers
Answer:
Will a raisin, paperclip, penny, small cork, ball of paper, and other small objects sink or float if they are placed in water, corn syrup and vegetable oil?
Write down what you think will happen when you place each object into the three different liquids.
What You Do:
Pour 150 ml of water into beaker #1, 150 ml of corn syrup into beaker #2, and 150 ml of vegetable oil into beaker #3. (If you are using glass jars, use 2/3 cup of liquid, which is approximately 150 ml.)
Gently set a raisin in each beaker. Does it sink or float? Write down what happens to the raisin in each beaker.
Take the raisins out of the beakers and try a different object, such as a paperclip or cork. Record what happens in each beaker.
Conclusions: Were your predictions right? Did the raisins and other objects sink and float when you expected them to? Did they float in one liquid and sink in another? Why do you think they acted the way they did?
The denser a liquid is, the easier it is for an object to float on it. If one of your objects floated in the corn syrup but sank in the water, what does that tell you about the densities of water and corn syrup? Take the experiment a step further to find out more.
