Is there any theory that can calculate that how much heat can be produced from a convex lens?

A convex lens cannot produce heat. It can focus incident heat to a smaller area so that it is more intense.

How to calculate heat produced in the resistance?
It takes approximately 4.184 Joules of heat to raise the temperature of 1 gram of water 1 degree C. 1 Joule is the energy of 1 Watt for 1 second (or 3,600,000 Joules equals 1 Kilowatt-hour). In more real world numbers: It takes 69.7 watts 1 minute to heat a liter of water 1 degree C; or 146.6 watts in 1 minute to heat a gallon of water 1 degree F. A watt is a watt, weather it comes from resistance, radiant or induction. The only variations will come from the efficientcy of the heat source's design and how it is being used.
A flat iron that has a resistance of 10 ohms is used for about 4 hourshow much heat is produced if the current is 10 amperes?
This can be calculate quite simply using the following steps. First calculate the power loss (as heat energy) from the iron using the relationship: P= I2R, P is power in Watts, I is current in Amps, R is resistance in Ohms. In this case P = 102 x 10 = 1000 W Next convert 4 hours into the standard time unit, seconds. 4 hours = 60 seconds per minute * 60 minutes per hour * 4 hours = 14400s Finally calculate how much heat energy is produced during this time using the relationship: E = Pt, P is power in Watts, E is energy in Joules, t is time in seconds. In this case E = 1000 x 14400 = 14400000 J Or more appropriately 14.4 MJ (megajoules). Hope this helps, Tom
What is the examples of energy produce nuclear reactor?
If you mean energy produced by nuclear reactors, then "heat" and "light" would be the answers (Just think of the sun)
What is laplas theory?
laplac theory is laplac correction about the statement of newton about sound heat in which newton said that when we talk there is no heat produced and no change in environmental heat but to correct this laplac said that there is heat produced when we talk and there is a change in environmental heat or temperature.
How do you calculate the molar heat of fusion?
Use Einstein's Theory of Special Relativity
What is the difference between heat of reaction and molar heat of reaction?
Heat of a reacion is the totall amount of heat a reaction produces. Molar heat of a reaction is the heat produced/mol if you have the molar hear of the reaction you can calculate the heat of the reaction based on the moles of reactants you have
Define enthalpy and how it is measured?
Enthalpy is a particular amount of heat that is produced or released at a given pressure. There are specific equations that must be used to calculate enthalpy.
Where solar heat is produced?
Solar heat is produced by stars. The people who live on Earth get their solar heat from the sun.
What is produced when energy transformation is produced?
heat
Is heat non-renewable?
That is dependent on how it is produced. Heat produced by burning fossil fuels in not renewable, but heat from concentrated solar is renewable.
Is anything produced in addition to light?
heat is produced
What is formula for thermal efficiency?
Thermal Eff = (mechanical heat produced/electrical heat produced) x 100%
What is heat and how is heat produced?
Heat is a form of energy that makes things hot.
What instrument can be used to calculate specific heat capacity?
A calorimeter can be used to calculate specific heat capacity.
Can you produce heat by friction process?
Heat IS produced by friction.
