Answer:

TRUE!!!

Explanation:

The transfer of thermal energy is called heat. Therefore, a heating system is a system for the transfer of thermal energy. Regardless of the type of heating system in a home, the basic function is the same: to produce thermal energy and transfer it to air throughout the house.

Answer:

true

Explanation:

because the thermal energy itself is heating. that's why we use thermal energy to transfer heat.

6. If 981 mL of a gas is heated from 335 K at constant pressure and the volume
storchak [24]

Answer:

1.5L

Explanation:

The new volume can be found by using the formula for Boyle's law which is

p1v1=p2v2

Since we are finding the new volume

v2= p1v1/p2

From the question we have

v2= 5x3/10=15/10= 3/5

We have the final answer as

1.5 L

The decomposition of hydrogen peroxide follows first order kinetics and has a rate constant of 2.54 x 10-4 s-1 at a certain temp
pav-90 [236]

<u>Answer:</u> The initial concentration of hydrogen peroxide at the given temperature is 0.399 M

<u>Explanation:</u>

Decomposition of hydrogen peroxide is following first order kinetics.

Rate law expression for first order kinetics is given by the equation:

k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}

where,  

k = rate constant = 2.54\times 10^{-4}s^{-1}

t = time taken for decay process = 855 s

[A_o] = initial amount of the reactant = ?

[A] = amount left after decay process =  0.321 M

Putting values in above equation, we get:

2.54\times 10^{-4}s^{-1}=\frac{2.303}{855s}\log \frac{[A_o]}{0.321}

[A_o]=0.399M

Hence, the initial concentration of hydrogen peroxide at the given temperature is 0.399 M
