The uncertainty principle is one of the most famous (and probably misunderstood) ideas in physics. It tells us that there is a fuzziness in nature, a fundamental limit to what we can know about the behaviour of quantum particles and, therefore, the smallest scales of nature. Of these scales, the most we can hope for is to calculate probabilities for where things are and how they will behave. Unlike Isaac Newton's clockwork universe, where everything follows clear-cut laws on how to move and prediction is easy if you know the starting conditions, the uncertainty principle enshrines a level of fuzziness into quantum theory.
This Should help you
A change in temperature is a sign that a chemical reaction has occurred. This occurs in an endothermic reaction. An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or simply the melting of ice cubes.
Hopefully im not too late :/
A is true
B is false
C is true
Answer:
The image is not accurate because
the heavier atoms are moving faster than the lighter ones
but the lighter ones must move faster than the heavier ones.
Explanation:
The image depicts the atoms of two different elements; atoms of lighter and heavier elements.
And the rate of diffusion (movement of atoms) of an element is inversely proportional to the square root of its molecular.
⇒ As the weight increases, the rate of diffusion (movement of atoms) decreases.
And as the weight decreases, the rate of diffusion (movement of atoms) increases.
so, heavier atoms move slowly compared to lighter atoms.
The image is not accurate because
the heavier atoms are moving faster than the lighter ones
but the lighter ones must move faster than the heavier ones.
