Ira Lisetskai [31]

Answer:

In each Amplify Science unit, students figure out

a phenomenon by asking questions, gathering

evidence, and coming up with an explanation of how

the phenomenon works. The Coherence Flowchart

visually represents the storyline of the unit, showing

the coherent flow of questions, evidence, and ideas that

support students as they build complex explanations

of the unit’s anchor phenomenon. The Coherence

Flowchart on the following pages (one chapter per

page) can be used to see the connections between

the questions that drive students’ experiences, the

evidence they gather, the ideas they figure out, and the

new questions that those ideas generate. The diagram

to the right explains the structure of a chapter in the

How much heat is required to increase the temperature of 10.0 grams of water 6.0oC? (The specific heat of water is 4.18 J/g x oC
scoray [572]

Heat required in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:<span>

Heat = mC (T2-T1)
Heat = 10.0 g (4.18 J/g-C ) ( 6.0 C )
<span>Heat = 250.8 J</span></span>

Find the pressure of a gas if the volume is 2.00 L, the temperature is 310 Kelvin and
kipiarov [429]

Answer:

25.42 atm

Explanation:

Data Given:

Volume of a gas ( V )= 2.00 L

temperature of a gas ( T ) =  310 K

number of moles (n) = 2​ mol

Pressure of a gas ( P ) = to be find

Solution:

Formula to be used

              PV= nRT

Rearrange the above formula

              P = nRT / V . . . . . . . . . . (1)

Where R is ideal gas constant

R = 0.08205 L atm mol⁻¹ K⁻¹

Put values in equation 1

                 P = nRT / V

                  P = 2 mol x 0.08205 L atm mol⁻¹ K⁻¹ x 310 k / 2 L

                  P = 50.84 L atm / 2 L

                  P = 25.42 atm

P ressure of gas (P) will be = 25.42 atm
