What do the particles do in thermal energy to make the temperature rise or fall?

Well, the particles gain energy from heat which makes the substance hotter.The more energy the particles gain, the hotter the substance.

When the substance is cooled the particles start to lose energy.The colder area that the substance is in, the more energy the particles lose.

A certain corner of a room is selected as the origin of a rectangular coordinate system. If a fly is crawling on an adjacent wal

lisov135 [29]

Answer:

S=2.693m

Explanation:

Let point $O$ be the origin of the room and the fly is crawling at point $P$ as shown in the attached photo:

#Distance of the fly from the corner of the room is defined as:

$OP=S=\sqrt{{(x_1-x_0)^2+(y_1+y_0)^2}$

#Substitute the coordinate values in the above equation:

$S=\sqrt{{(2.6m-0m)^2+(0.7m-0m)^2}}\\=\sqrt{7.25}\\=2.693m$

Hence, the distance of the fly from the corner of the room is 2.693m

When cooking frozen cheese ravioli, the directions say to put the 255 grams of filled pasta into 3 quarts of boiling water. Why

nadya68 [22]

Answer:

a. $T_f=95.14^{\circ}C$

b. $T_f=86.4^{\circ}C$

It is asked for 3 quarts of water because it prevents the temperature drop.

Explanation:

Given:

mass of frozen cheese, $m_c=255\ g$

quantity of water suggested for the given cheese, $m_w=3\ quarts\times 946.35=2839.05\ g$

initial temperature of cheese, $T_{ic}=-40^{\circ}\ C$

specific heat of cheese, $c_c=0.4\ cal.g^{-1}.^{\circ}C^{-1}$

initial temperature of water, $T_{iw}=100^{\circ}\ C$

a.

we have specific heat of water, $c_w=1\ cal.g^{-1}.^{\circ}C^{-1}$

so now, we use the heat equation to find the amount of heat exchange during the process:

$m_c\times c_c\times \Delta T=m_w\times c_w\times \Delta T$

$255\times 0.4\times (T_f-(-40))=2839.05\times 1\times (100-T_f)$

$T_f=95.14^{\circ}C$

b.

when using 1 quart of water:

$255\times 0.4\times (T_f-(-40))=946.35\times 1\times (100-T_f)$

$T_f=86.4^{\circ}C$

It is asked for 3 quarts of water because it prevents the temperature drop.
