_____ is a measure of the average kinetic energy of a gas. Density Enthalpy Pressure Temperature
Fiesta28 [93]

Answer:

Temperature

Explanation:

  • Temperature is a measure of the average kinetic energy of the particles in a sample of a gas.
  • Kinetic energy is the energy possessed by an object because of its motion. As an object absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.
  • When the temperature of a body or an object is increased and hence the heat, there is more movement or vibration of particles which translates to more kinetic energy.

A wave has a frequency of 4.00 hz and a wavelength of 10.0 m. What is the speed of the wave?
Sidana [21]

First use this equation to find the wave speed: vms== =τµ/ 0.4/ 0.001 20 / Then use the equation for solving frequency of a wavelength, and solve for wavelength λ = v/f = 20/100 = .2 m = 20 cm.

What is the density of a book that weighs 550 grams and has a volume of 0.5 liters
Oksi-84 [34.3K]

Answer:

1.1gcm^-3

Explanation:

density \:  =  \frac{mass}{volume}

0.5l = 0.5*1000

= 500cm^3

Density = 550/500

Density =

{1.1gcm}^{ - 3}

Element “yellowium” has three naturally occurring isotopes. Below are the masses and relative abundance of each isotope. Find th
katrin [286]
To find average atomic mass, multiply each isotope's atomic mass with its relative abundance and add it all up.

15.012*0.1423 + 16.988*0.3348 + 19.177*0.5229 = 17.851 (5 s.f.)
