Answer:
Charle's Law
Explanation:
<em>...cold it goes flat because the volume of air inside the ball has been reduced. </em>
<em />
In this scenario, the lower the temperature the lower the volume. This means that there's a direct proportional relationship between the volume and temperature.
This relationship is presented by Charles law. Charles law states that the volume occupied by a fixed mass of gas is directly proportional to its absolute temperature.
To find the IUPAC name for compounds, you must memorize prefixes and suffixes and other terms in determining or naming a compound. The IUPAC name for compound ZnO is Oxozinc or Zinc Oxide. I hope this helps you on your assignment.
Answer:
H = 4,034,250 J
Explanation:
Mass, m = 165kg = 165,000g (Converting to grams)
Initial temperature = 15.7°C
Final temperature = 95.7°C
Temperature change, ΔT = 95.7 - 15.7 = 50°C
Specific heat capacity, c = 0.489 J/g·°C
Heat = ?
All the parameters are related with the equation below;
H = m * c * ΔT
H = 165000 * 0.489 * 50
H = 4,034,250 J
Answer:
The answer is for your question is A
Answer:
15.1 g/mL
Explanation:
<em>The density of a substance is defined as the ratio of the mass of the substance and the volume of the substance. Mathematically, it is expressed as:</em>
Density = mass in grams/volume in mL
In this case, the mass of the metal = 30.2 g
Volume of the metal = volume of water displaced by the metal.
<em>The volume of water displaced by the metal can be calculated as the final volume of water after placing the metal - initial volume of water before placing the metal.</em>
Hence, volume of metal = 22.0 - 20.0 mL = 2.0 mL
Density of metal = 30.2/2.0 = 15.1 g/mL
The density of the metal is 15.1 g/mL
<u>The identity of the metal is not in the table.</u>
