The specific heat of copper is 0.385 j/(g · °c). if 34.2 g of copper, initially at 24.0°c, absorbs 4.689 kj, what will be the fi
julia-pushkina [17]
<span>We know the relation between heat and temperature follows the formula: Q = Ce * m * (Tf-Ti) , where Q is heat transfer, Ce is specific heat, m is mass, Tf is final temperature and Ti is initial temperature. Note that heat value is given in kj so we need to change to joules, then as heat is absorbed the final temperature will increase. 4,689 = 0.385 * 34.2 * (Tf-24) Tf = 4,689 / (0.385 * 34.2) + 24 =380.12ÂşC</span>

Mass = that which causes and object to have inertia

Newton’s First Law= a special case of Galileo’s Law of Inertia

Impulse= force multiplied by time

Momentum= velocity multiplied by mass

Velocity= momentum/mass

Newton’s Second Law= the acceleration of a mass directly proportional to the force acting on it
