An electric heater is used to heat 1 kg of water without energy losses. The specific heat capacity of water is 4.2 kJ kg-1K-1. What is the thermal energy taken to heat the
water from 25 °C to 95°C?

A: 294kj
B: 294j
C:136j
D:136kj

Since the pully is a simple machine so the mechanical advantage is a 1

From my calculation, i got 3.655moles

Following the american gauge wire standards ,the larger gauge number, the slimmer the wire and thus the smaller current carrying capacity it can have.then both statements would be incorrect, as they are saying the opposite of what it is actually is.(smaller gauge numbers have thicker wires and can carry more current)
