The heat capacity of a material shows the amount of heat that can be taken in before the material increases in temperature. Which statement about heat capacity is correct?
trust me if u want idc im just tryna help yall out
1:
A material with a greater heat capacity is better able to resist changes due to increases or decreases in heat.
2:
Silver holds on to its electrons less tightly than aluminum.
3:
copper
4:
Yes, it would. Aluminum is a conductor, and the glass would prevent electricity from transferring to a person holding the device.
5:
polycarbonate
helo is 100% correct
just asking, is this from CA?
What are your choices?
Ah, heat capacity, the superhero of temperature resistance! It's like a material's superpower against rising temperatures. Now, to answer your question with a touch of humor: the statement that is correct about heat capacity is that it's like a material's "coolness factor" - the higher the heat capacity, the cooler the material stays under pressure. It's like being the Fonz of thermal resistance! Just remember, don't mess with materials that have low heat capacity, they might get heated and start a hot mess! Stay cool!
To determine which statement about heat capacity is correct, let's break down the concept of heat capacity and understand how it relates to the amount of heat a material can absorb.
Heat capacity is defined as the amount of heat energy required to raise the temperature of a given substance by a certain amount. It is commonly denoted by the symbol "C" and is measured in units of energy per degree Celsius or Kelvin (e.g., joules per degree Celsius or kilojoules per Kelvin).
Here are two different statements about heat capacity:
1. "The heat capacity of a material remains constant regardless of its mass."
2. "The heat capacity of a material increases linearly with its mass."
To determine which statement is correct, we need to look at the properties of heat capacity. Heat capacity is an extensive property, meaning it depends on the mass of the substance. In other words, the more mass a material has, the higher its heat capacity.
Based on this information, we can conclude that statement 2 is correct: "The heat capacity of a material increases linearly with its mass."
To understand why this is true, we can consider the equation for heat capacity:
C = Q / ΔT
Where:
C is the heat capacity,
Q is the amount of heat energy absorbed or released by the material, and
ΔT is the change in temperature of the material.
From this equation, we can see that the heat capacity is the ratio of the heat absorbed or released to the change in temperature. As the mass of the material increases, it requires more heat energy to raise its temperature by a given amount, leading to a higher heat capacity.
Therefore, when comparing the two statements, statement 2 accurately describes the relationship between heat capacity and mass.
