Each cart below is pushed across a room with the same amount of force. Which cart will result in the greatest change in speed? F. A 75 kg cart being pushed with a 200 N force
G. A 125 kg box being pushed with a 200 N force
H. A 350 kg box being pushed with a 200 N force
J. A 450 kg cart being pushed with a 200 N force

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

a) the particles of the chair are strongly held together.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
