Answer:
THE HEAT CAPACITY OF THE CALORIMETER IS 3666.67 J/C
Explanation:
Mass = 2 g
Temperature difference = 32 C - 29 C = 3 C
Heat of combustion = 11 kJ/g
Heat capacity of the calorimeter = unknown
It is important to note that the heat of combustion of the reaction is the heat absorbed by the calorimeter in raising the mixture by 3 C
So therefore,
Heat = heat capacity * temperature difference
Heat capacity = Heat / temperature difference
Heat capacoty = 11 000 J / 3 C
Heat capacity = 3666.67 J/ C
Answer:
Explanation:
El calor se mide con un calorímetro y la temperatura se mide con un termómetro. Su unidad de medida. El calor se mide en julios, calorías y kilocalorías. La temperatura se mide en grados Kelvin (k), Celsius (C) o Fahrenheit (F).
A sample of oxygen occupies 1.00 × 10⁶ mL at 575 mmHg. If the pressure is increased to 1.25 atm, the volume decreases to 6.06 × 10⁵ mL.
<h3>What does Boyle's law state?</h3>
Boyle's law states that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
- Step 1: Convert the initial pressure to atm.
We will use the conversion factor 1 atm = 760 mmHg.
575 mmHg × 1 atm/760 mmHg = 0.757 atm
- Step 2: Calculate the final volume of the gas
A sample of oxygen occupies 1.00 × 10⁶ mL (V₁) at 0.757 atm (P₁).
If the pressure is increased to 1.25 atm (P₂), we can calculate the new volume (V₂) using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁ / P₂
V₂ = 0.757 atm × 1.00 × 10⁶ mL / 1.25 atm = 6.06 × 10⁵ mL
A sample of oxygen occupies 1.00 × 10⁶ mL at 575 mmHg. If the pressure is increased to 1.25 atm, the volume decreases to 6.06 × 10⁵ mL.
