The heat exchange in chemical reactions is due to a change in:

-kinetic energy

-enthalpy

-temperature

-physical properties

What is determined by motion and the spacing of particles?

What might cause convection currents in a hot spring?

The figure shows a zero-resistance rod sliding to the right on two zero-resistance rails separated by the distance L = 0.40 m. The rails are connected by a 10.5-Ω resistor, and the entire system is in a uniform magnetic field with a magnitude of 0.
