Answer:
When the temperature of an object increase, the object's particle move faster.
Explanation:
Energy in form of the heat can be absorbed by the object, energy is translated to object's particles. In that moment, energy is transformed in another form - kinetic energy. Kinetic energy manifest as a faster particle movement ( or vibration ).
ANSWER Since 1.0 × 10 -7 has two significant figures, the pH can be reported as 7.00. A logarithmic scale condenses the range of acidity to numbers that are easy to use. Consider a solution with [H + ] = 1.0 × 10 -4 M. That is a hydrogen-ion concentration that is 1000 times higher than the concentration in pure water.
Answer:
45.0 L is the volume of gas will the balloon contain at 1.35 atm and 253 K.
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 25.0 L
V₂ = ?
P₁ = 2575 mm Hg
Also, P (atm) = P (mm Hg) / 760
P₁ = 2575 / 760 atm = 3.39 atm
P₂ = 1.35 atm
T₁ = 353 K
T₂ = 253 K
Using above equation as:
Solving for V₂ , we get:
<u>V₂ = 45.0 L</u>
45.0 L is the volume of gas will the balloon contain at 1.35 atm and 253 K.
