Asample of argon has a volume of 5.0 l

and the pressure is 0.92 atm. if the final temperature is 300.° c, the final volume is 5.7 l, and the final

pressure is .800 atm, what was the initial temperature of the argon?

Standing in the sunlight and feeling the heat on your face (uv radiation is entering the skin, converting to infrared radiation, and is absorbed by your tissues)orstanding near a fire and feeling the heat on your skin (infrared radiation transfer)

What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.
