There is not enough information in this problem to answer the question. You must know the mass of the iron to find the amount of joules used to heat the iron.
The amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy is 42,2g H2O.
Yes cactus do absorb radiation. But they do it for a limited range.
depends on the amount of each but assuming equal amounts of each; 53.5 degrees celsius
On the amount of radiation emitted; on how close the individual is to the source of the radiation; on any objects in between which might absorb part of the radiation.
When converting from Celsius to Kelvin you always add 273.15 and subtract the same amount when converting from Kelvin to Celsius thus: -259+273.15=14.15 The answer is 14.15 Kelvin
The amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy is 42,2g H2O.
black absorbs the most

To convert kelvin to Celsius, subtract 273.15 from kelvin. So if you are at 273.15 kelvin, you are at zero degrees Celsius. The above is almost true. 0 degrees Kelvin is equivalent to (minus) - 273.15 degrees Celsius. So you would need to add that amount to reveal the temperature in degrees Celsius.
calulate the amount of heat released when 25 gram of water at 25 degrees Celsius cools to 0.0 degrees celsius
Yes, dark clothing absorbs the most.
100 degrees Celsius

The lenses absorb a very small amount of light, transmitting most of it. If the frame of the glasses is made of a dark material, it will absorb most light.
20 degrees Celsius is a temperature or a temperature range on the Celsius scale, where 0 is the freezing point of water and 100 is the boiling point of water. If the air temperature is 20 degrees Celsius, the weather is cool but not cold. If a pot of water is raised in temperature by 20 degrees Celsius it is heated by a set amount. 20 degrees Celsius is the same as 68 degrees Fahrenheit.
Fahrenheit would change 10.8 degrees.
From my experience, there wouldn't be an actual fixed amount, simply because the amount of water absorb is never truly constant. Also, each towel absorbs a slightly different amount of water. This makes it almost impossible to get a constant, fixed amount. I hope I was helpful.
