well because of the salt in the water that is why it takes longer to freeze.
Explanation:
To test for it, use two containers, one which contains only water and the second should be one with salt solution.
then experiment the time each take to freeze.
hope it helps .
Answer:
Option A, hydrogenous sediments
Explanation:
Hydrogenous sediments are made up of minerals suspended in water that precipitates out in due course of time thereby forming minerals. These sediments are found in a very small amount and generally constitute 0.5 to 1 % of the total ocean sediments. While cosmogenous sediments are made up of space materials falling on earth, biogenous sediments are made up of living organism remains, lithogenous sediments are made up of land. All manganese, ferromanganese and phosphite nodules are hydrogenous
Hence, option A is correct
The controversy mostly originates from that fact that the studied embryonic stem cells come from human embryos, which raises a lot of ethical questions among people.
Answer:
L
Explanation:
The details tell us that the substance starts out and its atoms are "close together and cannot slide past one another." This describes a solid: liquids and gases' atoms can move freely, but solids' atoms cannot move. So we know that the substance starts as a solid.
That means the answer must be L or P, because the solid needs to change into something else.
Then the substance gains energy and it can fill its container. Well, this could be either gas or liquid! So it's a good thing that <u>only L is an answer choice,</u> because that means L is correct and the change is from solid -> gas.
