2H2O->2H2+O2
This balanced chemical equation represents the decomposition of water into hydrogen gas and oxygen gas
Because it's placed in the lasagna, the thermal energy is transferred by conduction. Remember, convection is transfer of heat through fluids (liquids and gases), and radiation is just transfer of heat through air.
No, gravity does not have mass, it behaves like a particle without mass
When the velocity is increasing the acceleration increases too
