Answer:

Plants release more carbon dioxide into atmosphere than expected. ... Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesishesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

I don’t think plants release carbon dioxide into the atmosphere, do you mean oxygen? Because if you did, plants do photosynthesis and release oxygen in the environment.

Two systems with heat capacities 19.9 J mol-1 K-1 and 28.2 ] mol 1 K-1 respectively interact thermally and come to an equilibriu

MAVERICK [17]

Answer : The initial temperature of system 2 is, $19.415^oC$

Explanation :

In this problem we assumed that the total energy of the combined systems remains constant.

$-q_1=q_2$

$m\times c_1\times (T_f-T_1)=-m\times c_2\times (T_f-T_2)$

The mass remains same.

where,

$C_1$ = heat capacity of system 1 = 19.9 J/mole.K

$C_2$ = heat capacity of system 2 = 28.2 J/mole.K

$T_f$ = final temperature of system = $30^oC=273+30=303K$

$T_1$ = initial temperature of system 1 = $45^oC=273+45=318K$

$T_2$ = initial temperature of system 2 = ?

Now put all the given values in the above formula, we get

$-19.9J/mole.K\times (303-318)K=28.2J/mole.K\times (303-T_2)K$

$T_2=292.415K$

$T_2=292.415-273=19.415^oC$

Therefore, the initial temperature of system 2 is, $19.415^oC$

Airida [17]

Answer:

120 liters

Explanation:

From the question,

Applying boyles law

PV = P'V'................ Equation 1

Where P = initial pressure, V = Initial Volume, P' = Final pressure, V' = Final Volume.

make V' The subject of the equation

V' = PV/P'............. Equation 2

Given: P = 2 kpa, V = 60 liters, P' = 1 kpa

Substitute these values into equation 2

V' = (2×60)/1

V' = 120 liters

Hence the right option is A. 120 liters
