As particles move faster it would feel cool to touch true or false brainly
1 answer:
Answer: False
Explanation: The kinetic energy of the molecules is the energy possessed by virtue of motion of particles.
Kinetic energy of the particles is directly proportional to the temperature of the gas.
where T= temperature
R= gas constant
Thus if the particles are moving faster that means the kinetic energy is high, the temperature must be higher and the particles must feel hot to touch.

The large piece of jewelry that has a mass of 132.6 g and when is submerged in a graduated cylinder that initially contains 48.6 ml water and the volume increases to 61.2 ml once the piece of jewelry is submerged, has a density of: 10.523 g/ml
To solve this problem the formulas and the procedures that we have to use are:
- v = v(f)-v(i)
- d = m/v
Where:
- d= density
- m= mass
- v= volume
- v(f) = final volume
- v(i) = initial volume
Information about the problem:
- m = 132.6 g
- v(i) = 48.6 ml
- v(f) = 61.2 ml
- v = ?
- d =?
Applying the volume formula we get:
v = v(f)-v(i)
v = 61.2 ml - 48.6 ml
v = 12.6 ml
Applying the density formula we get:
d = m/v
d = 132.6 g/12.6 ml
d = 10.523 g/ml
<h3>What is density?</h3>It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.
