Jet001 [13]

Two blocks of platinum have a temperature of 200 Celsius. Both the blocks have the same amount of thermal energy because both are metals which conducts heat energy throughout their bodies.

<h3>What is conduction?</h3>

Conduction is the process by which heat energy is transmitted between neighboring atoms or molecules. We know that metals are the good conductors of heat and electricity so if one part absorb heat, it will spread to the whole body so we can conclude that the thermal energy will remain the same amount throughout the whole body.

The following equation lnN - N₀ = -kt Of time t is plotted on x-axis and lnN is plotted on y-axis, what are the slopes and y-int
stepladder [879]

Answer:

-k slope

The term No is the y intercept(does not mean NO) y-intercept

Explanation:

For a straight line graph, the normal equation could be written as

y = mx + c

Where m is the slope and c is the y intercept.

Writing the equation is the form of y = mx + c gives the following;

lnN = -kt + No

As obtained from the question, t is plotted in the x-axis, while lnN is the plot on the y-axis.

Now, we are asked to obtain the slope and the y-intercept. It can be seen that the slope is the coefficient of the term x in this case t. Hence, our slope is -k.

The y-intercept is the other term which in this case is No
