What has the greater density a cube of water measuring 1cmX1cmX1cm and having a mass of 1g or a block of plastic measuring 2cmX3cmX1cm with a mass of 4g?
Density = Mass/Volume. For water: 1/(1*1*1) = 1/1 = 1 g/cm3 For plastic: 4/(2*3*1) = 4/6 =2/3 g/cm3. So the water has the greater density.
What is the formula for finding the volume of a copper?
If you refer to a copper coin, simply place it in a measuring glass of water and work out the difference between the start and final volumes; that is the volume of the coin.
What is the advantage of measuring volume rather than length of tumours?
Think of a plastic bag filled with water. It makes more sense to describe the amount of water within the bag by it's volume vice the bag's dimensions.
How do you calculate the volume of irregular solids Describe please An irregular solid is like a toy car so how would you measure the volume of that Dont understand need help click on and find out?
The volumes of small irregular solids are usually easily measured by measuring the volume of fluid displaced when they are immersed in a liquid. For example: You would have to put the object in a measuring glass with water in it. (~1/3 filled) Put the object in it and then get the number from the measuring glass (beaker etc. mostly beaker) and that is how you measure a irregular solid!
Explain two ways to find the volume of a plastic cube?
Measure the length of the edge of the cube and multiply this by itself 3 times.Fill a measuring jug with enough water to cover the cube. Measure the level of water. Immerse the cube in the water in jug and measure the level of the water. The difference in level is the volume of the cube.
Which is a better conductor glass or plastic?
Glass is a better insulator than plastic. Plastic is used on wire for insulation purposes because of its flexibility, where as glass is not. Glass is used as insulators for holding wires to cross arms on power poles as plastic would not stand up to the weather year after year.
Which is the best unit for measuring the amount of water in a drinking glass?
The best unit of measure to use when measuring the amount of water in a drinking glass is ounces. A liquid measuring cup can be used to measure the ounces of water.
Should water be served in plastic bottle glass or plastic cup?
Glass would be healthier
What are some good containers for holding water?
a beaker or a measuring cup are a few of the simple ways to collect rain water. -Emma(:
What effect does salt water have on glass and plastic?
salt corrodes glass
Do you think that glass is cleaner than plastic in water bottles?
I would say glass. Glass is nonporous and easily cleaned and disinfected. Plastic is soft and the molecules making up the plastic bottle may leach into the water.
What measuring a glass of orange juice?
2 ml
Which holds more water a one cup measuring cup or a glass that holds one pint?
a glass that holds one pint
What are some transparent objects?
Some transparent objects are water, air, and clear glass.
How do you differentiate between plastic and glass containers?
Throw them at the ground. The glass will shatter. Plastic will not. dont try this at home... It wont hold water.
Glass or plastic what keeps water colder?
Metal - very good conductor of heat. Not a good insulator at all (Don't wrap cans in aluminum foil.) Glass - A little better resistor of heat energy transfer but still not great. Plastic - Depending on the exact material, plastic is probably your best bet. Especially if it's a foam of some sort; the air bubbles in the foam create barriers that heat energy has to cross to be able to escape.
For water in glass plastic or styrofoam cups - which will freeze fastest?
Assuming they are the same or similar shape and volume, water in glass would freeze first, then plastic then foam. Foam allows transfer of heat out of water more slowly than plastic and the glass probably has the highest rate of heat radiation of the three.
