Answer:
Temperature
Explanation:
A<em> calorimeter </em>is an scientific instrument used for calorimetry, the process of measuring heat. The processes commonly studied by calorimetry are phase changes, chemical reactions, or measurements of heat capacity. For any of those processes the measured property is <em>temperature</em>.
I believe the answer is 2
Answer:
1.17 L
Explanation:
Step 1: Given data
- Initial volume (V₁): 1.50 L
- Initial pressure (P₁): 1.10 atm
- Initial temperature (T₁): 25 °C
- Final pressure (P₂): 1.50 atm
- Final temperature (T₂): 45 °C
Step 2: Convert the temperatures to the Kelvin scale
We will use the following expression.
K = °C + 273.15
K = 25°C + 273.15 = 298 K
K = 45°C + 273.15 = 318 K
Step 3: Calculate the final volume of the neon gas
If we assume ideal behavior, we can calculate the final volume of the neon gas using the combined gas law.
P₁ × V₁ / T₁ = P₂ × V₂ / T₂
V₂ = P₁ × V₁ × T₂ / T₁ × P₂
V₂ = 1.10 atm × 1.50 L × 318 K / 298 K × 1.50 atm = 1.17 L
All matter is made of tiny particles called atoms, molecules and ions; the tiny particles in solids are tightly packed and can only vibrate. The particles in liquids also vibrate but are able to move around by rolling over each other and sliding around. In gases, the particles move freely with rapid, random motion.
