__ Conduction  __ In heat transfer, conduction is the transfer of ﻿﻿  thermal energy  ﻿﻿   between molecules in a substance due to a temperature gradient. It always takes place from a higher temperature to a region of lower temperature, and acts to equalize the temperature differences. Conduction takes place in all forms of matter. __ Radiation  __ Radiation describes a process in which energetic particles or waves travel through a space. There are two distinct types of radiation; ionizing and non-ionizing. The word radiation is commonly used in reference to ionizing radiation only (i.e., having sufficient energy to ionize an atom), __ Convection  __ Convection is the movement of molecules within fluids (i.e. liquids, gases). It cannot take place in solids, since neither bulk current flows nor significant diffusion can take place in solids. Convection is one of the major modes of heat transfer ﻿  and  ﻿﻿  mass transfer.

in todays experiment we found out that oil heats more than water does, even though they are the same amout of liquid.

CONCLUSION: 1. Describe one possible trend in the data.

The different cans, hight & colour
2. Explain why we can only say it is a 'possible' trend.

DISCUSSION:
1. Explain the trend above in terms of how heat moves.
