Answer: energy of infrared radiation=13.75×10^-20J
Energy of ultraviolet radiation=8.5×10^-19J
Energy of xrays=3.7×10^-17J
Explanation:
Energy of radiation= h×c/wavelength
h=6.6×10^-34 Js
c=3×10^8 ms-1
For infrared= 6.6×10-34×3×10^8/1.44×10^-6=13.75×10^-20J
For ultraviolet= 6.6×10^-34 × 3×10^8/233×10^-9=8.5×10^-19J
For xrays= 6.6×10^-34×3×10^-8/5.34×10-9=3.7×10^-17J
If you increase the temperature the air will try to expand. Since it is sealed and the air can't expand, it will apply higher pressure to the can because it will want to burst out. It works the other way around, if you cool it down it will lower the pressure.
