What are 3 physical features that change during the life of a star?
Within the lifetime of a star, its colour, its size, and the amount of heat it radiates will all change.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
How does a change in temperature affect the melting of ice?
A change in temperature affects the melting of ice by either speeding up or slowing down the process. When the temperature increases, the ice absorbs heat energy and melts faster. Conversely, when the temperature decreases, the ice absorbs less heat energy and melts slower.
How does the temperature of 33 grams of graphite change when it absorbs 350 joules of thermal energy?
The temperature of graphite will increase because it absorbs thermal energy. The temperature increase can be calculated using the specific heat capacity of graphite.
When a substance loses or absorbs energy its temperature can change true or false?
True. When a substance loses energy, its temperature can decrease, while when it absorbs energy, its temperature can increase. This is because energy is transferred as heat, which can lead to changes in temperature.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
What A steep slope on a phase-change graph indicates?
Different
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
why does earth air temperature vary greatly during the day while its ocean temperature varies only slighly?
But the global temperature mainly depends on how much energy the planet receives from the Sun and how much it radiates back into space—quantities that change very little. ... A one-degree global change is significant because it takes a vast amount of heat to warm all the oceans, atmosphere, and land by that much.
What is the relationship between specific heat and latent heat in the context of thermal energy transfer?
Specific heat and latent heat are both properties of a substance that determine how it absorbs or releases thermal energy. Specific heat refers to the amount of heat required to raise the temperature of a substance by a certain amount, while latent heat is the amount of heat needed to change the state of a substance without a change in temperature. In thermal energy transfer, specific heat affects the temperature change of a substance, while latent heat is involved in phase changes such as melting or boiling.
What is an amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy?
The amount of heat energy required to change the temperature of a substance is given by the formula: Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. Given that Q = 2646 J, ΔT = 15 °C, and for water c = 4.18 J/g°C, we can calculate the mass of water as follows: 2646 J = m * 4.18 J/g°C * 15 °C. Solving for m, we find that the mass of water required is approximately 40 g.
Is there a change in temperature when ammonium chloride is added to water and being stirred?
Yes, there is a change in temperature when ammonium chloride is added to water and stirred. Ammonium chloride dissolves in water endothermically, meaning it absorbs heat from its surroundings to break down into its ionic components. This absorption of heat causes a decrease in temperature of the solution.
