Calculate the heat energy needed to change the temperature of 2 kg of copper from 10c to 110c

How to tell if a molecule is polar or nonpolar with electronegativity

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?

Which type of reaction is shown in this energy diagram ?
