A 13.5g sample of gold is heated and then placed in a container of 60.0g H20. The
temperature of water increases from 19.0°C to 20.0°C. What was the initial
temperature of the gold metal sample? (The specific heat of gold is 0.13J/gºC).

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
