Can an object contain heat? Why or why not?

1 answer:

8 0

Every object has thermal energy (better word than heat, since we associate that with high temperatures). This is actually the molecules vibrating, moving a lot. More thermal energy means more vibrating, and thus also expanding in volume.

What is the frequency of blue light that has a wavelength of 473nm?

ankoles [38]

Answer:

6.34 x 19^14 Hz

Explanation:

Wavelength, λ = 473 nm = 473 x 10^-9 m

the relation between the frequency and the wavelength is given by

v = f x λ

where, v is the velocity of light in vacuum which is equal to 3 x 10^8 m/s.

So, f = v / λ

f = ( 3 x 10^8) / ( 473 x 10^-9)

f = 6.34 x 19^14 Hz

At a pressure of one atmosphere methane boils at −161°C and freezes at −182.5°C. Consider a temperature scale where the boiling

lawyer [7]

Answer:

$-421.627906977\^{\circ}M$

Explanation:

Absolute zero in the Kelvin scale = -273.15 °C

Temperature difference in the boiling and freezing point

$-161-(-182.5)=21.5\ ^{\circ}C$

Change in 21.5°C = Change of 100°C in M

$1^{\circ}C=\dfrac{100}{21.5}=4.6511627907\ ^{\circ}M$

Difference in the Celsius scale

$-182.5-(-273.15)=90.65\ ^{\circ}C$

Change in $90.65\ ^{\circ}C$ corresponds to

$4.6511627907\times 90.65=421.627906977\ ^{\circ}M$

Therefore the absolute zero in the Methane scale is

$-421.627906977\ ^{\circ}M$
