What is the melting point of a battery?
Melting points are of pure substances, not of objects made out of many, many substances. Eg. A news paper or an aeroplain don't have a melting point. Neither do batteries. But be carefull in warming them up above 50oC !!
What do physical properties have in common the length of a snake the melting point of gold and the volume of lemonade?
They are measurable.
Which have higher boiling points organic or inorganic compounds?
Due to the different density of objects there will be a variety of melting points
Why do scientists wear close toed shoes during labs?
Scientists wear closed toed shoes during labs to protect their feet from objects and substances that might be dropped, spilled, splashed, etc. Where the objects might be particularly heavy they may even choose to use "steel-toed" shoes to protect their toes from crushing.
What objects slow the melting of ice?
gelatin. it is used for slow melt popsicles.

Why scientists use equipment?
Scientists use equipment so that they can figure out different substances in different objects which have not or have been tested

They are measurable.
How do you get two different size objects to be the same weight?
-- form them from substances with different densities Example: a small stone and a large ball of cotton
Which have higher boiling points organic or inorganic compounds?
Due to the different density of objects there will be a variety of melting points
Do objects of the same size and shape have the same mass?
No, not unless they are made of the same substance. Different substances have different densities, which means that the same volumes will have different masses.
What do they call all objects that exist?
Objects that exist, scientifically are substances.
What is a substances that give color to objects such as paint hair and fibber are called?
what is a substances that give color to objects,such as paint,hair,and fibber,are called

What is meant by greater mobility of resources?
Melting point of objects
Can objects have different weight but same volume?
Yes. A good example would be styrofoam and steel. The same volume of each of these substances would make for vastly different weights.
Why does adding the same amount of heat to two different Objects does not necessarily produce the same increase in Temperature?
Difference in desity of the matrials the objects are made of.
