The main idea of the kinetic theory of heat is
Heat is transferred by the interaction of moving particles
Explanation:
Kinetic theory is one of the most foundation concepts in both physics and thermodynamics of chemistry which is that the kinetic properties of a particle decide the energy and the heat it generates and there is correlation between the three.
The heat in particles is generated by their movement so the more particles move the more heat is generated and vice versa is also true for them. More movement in particles also means more energy.
thus the heat made is transferred by the interaction of these moving particles.
Q = m C ΔT where:
m : mass in grams (75.0 g)
C : specific heat capacity of gold (0.129 J / g °C)
Δ T : Final T - Initial T (250 - 150) = 100°C
Q = 75.0 * 0.129 * 100 = 967.5 J
I believe the answer is >0, but it could be <0
Explanation:
Sodium metal reacts rapidly with water to form a colourless basic solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide.
