diamong [38]2 years ago
6 0

Answer:

Joule's law is verified using Joule's calorimeter. .

Explanation:

Two thirds of the volume of the calorimeter is filled with water. The calorimeter is enclosed in a wooden box to minimise loss of heat. A battery (Bt), a key (K), a rheostat (Rh) and an ammeter (A) are connected in series with the calorimeter

In a certain chemical process, a lab technician supplies 292 J of heat to a system. At the same time, 68.0 J of work are done on
vekshin1

Answer:

The increase in the internal energy of the system is 360 Joules.

Explanation:

Given that,

Heat supplied to a system, Q = 292 J

Work done on the system by its surroundings, W = 68 J

We need to find the increase in the internal energy of the system. It can be given by first law of thermodynamics. It is given by :

dE=dQ+dW\\\\dE=292\ J+68\ J\\\\dE=360\ J

So, the increase in the internal energy of the system is 360 Joules. Hence, this is the required solution.

A 5.00 g bullet traveling 355 m/s is stopped by lodging in the side of a building. The heat produced is shared between the build
steposvetlana [31]

Answer:

Explanation:

Given

mass of bullet m=5\ gm

speed of bullet v=355\ m/s

bullet is stopped by building and heat produced is shared between building and bullet

Kinetic Energy of bullet is converted into Thermal energy

Kinetic Energy of bullet K=\frac{1}{2}mv^2

K=0.5\times 5\times 10^{-3}\times (355)^2

K=315.06\ J

So 315.06 J of Energy is converted in to thermal energy
