Answer:

Conceptual.

Explanation:

Conceptual method includes a diagrammatic representation of biological life cycle. It helps in better understanding of the life cycle of an organism. Betty is also using conceptual method to illustrate the life cycle of butterfly. The diagrams show various stages of growth of butterfly in a picture form. This enables the students to easily understand the phenomena.

How would local residents of a place be affected by changes in the hydrosphere? (please help!!)
lesya692 [45]

Answer:

Humans have impacted the hydrosphere drastically and will only continue to due so based on population needs. Global climate change, water pollution, damming of rivers, wetland drainage, reduction in stream flow, and irrigation have all exerted pressure on the hydrosphere's existing freshwater systems.

Hope it helps :)

A gas occupies 200ml at a temperature of 26 degrees Celsius and 76mmHg pressure. Find the volume at -3degree Celsius with the pr
sergey [27]

Answer:

184.62 ml

Explanation:

Let p_1, v_1, and T_1 be the initial and p_2, v_2, and T_2 be the final pressure, volume, and temperature of the gas respectively.

Given that the pressure remains constant, so

p_1=p_2 ...(i)

v_1 = 200 ml

T_1= 26 ^{\circ}C = 273+26 =299 K

T_2= 3 ^{\circ}C = 273+3 =276 K

From the ideal gas equation, pv=mRT

Where p is the pressure, v is the volume, T is the temperature in Kelvin, m is the mass of air in kg, R is the specific gas constant.

For the initial condition,

p_1v_1=mRT_1 \\\\mR= \frac{p_1v_1}{T_1}\cdots(ii)

For the final condition,

p_2v_2=mRT_2 \\\\mR= \frac{p_2v_2}{T_2}\cdots(iii)

Equating equation (i), and (ii)

\frac{p_1v_1}{T_1}=\frac{p_2v_2}{T_2}

\frac{v_1}{T_1}=\frac{v_2}{T_2}  [from equation (i)]

v_2=\frac{T_2}{T_1} \times v_1

Putting all the given values, we have

v_2=\frac{276}{299} \times 200 = 184.62 \; ml

Hence, the volume of the gas at 3 degrees Celsius is 184.62 ml.

A block of metal has a volume of 14.0in3 and weighs 5.26lb .
natulia [17]
Mass of block, m = 5.26 lb  
1 lb = 453.592 g
 5.26 lb = 2385.896 g
V = 14 in3
 1 in = 2.5 cm
 1 in3 = 15.625 cm3
 14 in3 = 218.75 cm3


Density = mass/volume
 = 2358.896 / 218.75
 = 10.783 g/cm3
