How can you tell whether one glass of water has more thermal energy than another, identical glass of water

You can know which one has more thermal energy by testing the temperature, if it is warmer the more energy it has because the particles are going faster than they would if it was cold. because, when its cold the particles slow down until they are so cold they are frozen. (ice).

According to my school book thermal energy is the total kinetic energy of the particles that make up a substance thermal energy is measured in joules know that this is different from the temperature for it is the average kinetic energy while the thermal energy is the total kinetic energy.not done answering this

What is the pressure in a 5.00 L tank with<br> 7.10 moles of oxygen at 39.3 °C?

Katena32 [7]

Answer:

36.4 atm

Explanation:

To find the pressure, you need to use the Ideal Gas Law. The equation looks like this:

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = constant (0.0821 L*atm/mol*K)

-----> T = temperature (K)

Before you can plug the given values into the equation, you first need to convert Celsius to Kelvin.

P = ? atm R = 0.0821 L*atm/mol*K

V = 5.00 L T = 393 °C + 273.15 = 312.45 K

n = 7.10 moles

PV = nRT

P(5.00 L) = (7.10 moles)(0.0821 L*atm/mol*K)(312.45 K)

P(5.00 L) = 182.130

P = 36.4 atm

The frequency of an x-ray wave is 3.0 x 1012MHz. Its wave speed is 3.0x 108m/s. Calculate the wavelength of the x-ray wave below

jasenka [17]

Answer: The wavelength of the x-ray wave is $10^{-10}m$

Explanation:

To calculate the wavelength of light, we use the equation:

$\lambda=\frac{c}{\nu}$

where,

$\lambda$ = wavelength of the light = ?

c = speed of x-ray= $3.0\times 10^8m/s$

$\nu$ = frequency of x-ray = $3.0\times 10^{12}MHz=3.0\times 10^{18}Hz= 3.0\times 10^{18}s^{-1}$ $(1Hz=1s^{-1})$

Putting in the values:

$\lambda=\frac{3.0\times 10^8m/s}{3.0\times 10^{18}s^{-1}}=10^{-10}m$

Thus the wavelength of the x-ray wave is $10^{-10}m$
