Heat = m x c x Δθ
2000 = 2 x c x 5
Specific heat c = 200 J / Kg / C
The molecules making up object collide with the molecules of the other and some of the kinetic energy from a warmer object is transferred to the cooler one.
The 'North pole' of any magnet is the one that would be attracted to the Earth's North magnetic pole. In that sense, they are just labels that identify the opposite magnetic force produced at each end of the magnet. The Earth'smagnetic field also has poles, North and South. more at study.com
