If we are tying to heat 90 g of water to a boil starting at 22 degrees C, how much energy in joules will we need?
The 'c' value for water is 4.18J/gC
Q=mC(delta)T
08276)
O 8000 K)

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

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.

i think its 100

i hope this !
