Solids
Do solids have a definite shape or volume
Both
Can liquid form intermolecular bonds
Yes
what is average speed of particles
Temperature
What of brownian motion
That the particles of an atom are always moving
What is a sine wave
A repeatin patter
What is specific heat compacity
Amount of heat required to change a given mass substance by one degree Celsius
The grand total kinetic energy in a given object
What is an electron
Part of atom with negative charge
What is a measurement of amplitude
Distance
Is ice denser or less dense than water
Less dense
How is water unique
When it freezes it expands and it’s specific heat compacity is insane
I’m what direction does heat travel
From hot to cold
What is Thompson crt expierament
He shot a electricity through a beam and put a positive magnet underneath and some of the electricity bent downwards(discovery of the electron)
What is the difference between a red and blue shift
Red shift frequency’s going away from you blue shift is them getting closer
Why do we say a spring is elastic
It can be attracted but returns to original shape
What is the neutral layer of a beam holding an uneven load
The middle no compressions or tensions
What is tempature of boiling water on a kelvin scale
373.15k
Do two isotopes have the same atomic #and why so
Yea because they always the same number on protons
In Doppler affect does the frequency or speed change
frequency
In what following ways is weight density different than mass density?
A. It takes volume into account
B. It takes mass into account
C. It takes acceleration into account
D. None of these
It takes acceleration into account
What is the density of an object that has of 30 grams and a volume of 20cm use correct unita
1.5g/cm2
Heat is measured in what other physical science calculation
Work/joules
What is the difference between atomic mass # and atomic mass
atomic mass is number of neutrons plus number of protons and takes only one atom into account but atomic mass number the average of all isotopes
