When a substance is heated the particles gain energy and spread out, creating more volume (spaces between the particles. So what about the mass of the substance? What happens to the mass of a substance when it is heated?
mass increases
mass decreases
mass remains the same
mass is lost
Solids made of different metals were all heated to 100o C to determine how their volume and length would be affected. Which statement describes the most likely outcome of this experiment.
All the volumes changed the same amount and the lengths remained constant
All the volumes changed, but each substance was the same length
Only some of the volumes changed with thier lengths being increased
All of the volumes changed and so did thier lengths
An experiment testing the affect of heat on different liquids was performed by some students. Which of the following variables would have been the manipulated variable.
The amount of heat used
The size and type pf glass tubing each liquid would rise
The different types of liquid
The different levels of each of the liquids in the glass tubing
Look at the experiment that the students set up to determine if a gas expands when heated. The experiment didn't work because the students were missing an important element to get the results they predicted. What was missing?
proper safety equipment
A larger balloon
A larger flask was needed
A heat source
A balloon filled with helium was put into a freezer to determine what the effect the lowering of the temperature would have on a gas. The responding variable in this experiment was the ...
