How will the final velocity be greater then the initial velocity?
It doesn't necessarily mean that the final velocity is always greater than the initial, if the initial velocity was at rest or 0 m/s then any form of movement would be greater. In cases where the final is smaller is like running into a wall or a decrease in acceleration.
What does mucho mucho calor mean?
very very hot
What does the word defy actually mean?
'To defy' could mean all sorts of things depending on a specific context. It could mean 'to provoke', 'to diss', 'to challenge', 'to incite', and 'to aggravate'.
What does the word throughflow mean?
throughflow means that water flows
What does mucho caliente mean?
"Mucho caliente" means "much hot," which is grammatically incorrect. It's correct to say:muy caliente (very hot)ormucho calor (much heat)
Which liquid has a specific gravity greater than 3.52?
Mercury is a liquid with a specific gravity greater than 3.52.
Why does water have a high specific heat capacity?
Water has a high specific heat because of the hydrogen bonds acting on the molecules. These hygrogen bonds can "store" thermal energy, and this allows water to absorb or release a lot of heat without a large change in temperature.
What does a specific gravity of 1.030 mean?
It's a density measurement relative to (standard) water. Water is given a 1.00. Things that would sink have greater than 1.00 specific gravity (not accouting for shape).
Does a high or low specific heat mean the substance heats up so fast?
A low specific heat means the substance heats up faster, as it requires less energy to raise its temperature. Conversely, a substance with a high specific heat requires more energy to raise its temperature, so it heats up more slowly.
It influences the amount of heat needed for matter to reach a certain temperature when a substance expands or contracts however it does not change what is it?
I guess you mean the specific heat capacity of a substance. Water is 1 calorie per gram, for other substances the quoted figure is often called the 'specific heat' which just means the ratio of its own heat capacity to that of water.
Water has a temp of 4.184 and copper has a temp of 0.387. Does it takes more heat to raise the temp of the copper molecule?
Yes, it takes more heat to raise the temperature of copper than water because copper has a lower specific heat capacity than water. This means that it requires less heat to raise the temperature of water compared to copper for the same mass of the substance.
Explain how the specific heat of a substance is determined?
specific heat is the amount of heat to be absorbed required to raise a substance 1 degree celsius. And by heat being absorbed, i mean energy, because specific heat is measured in joules
What does it mean to have a higher specific heat?
Having a higher specific heat means that a substance requires more energy to change its temperature compared to a substance with a lower specific heat. This property can help regulate temperature changes, making substances with higher specific heat more resistant to rapid temperature fluctuations.
The temperature of 15 grams of water is increased by 3.0 Celsius degrees How much heat in Joules was absorbed by the water?
To calculate the heat absorbed by the water, you can use the formula: heat = mass * specific heat capacity * temperature change. First, determine the specific heat capacity of water (4.18 J/g°C). Then, plug in the values: heat = 15 g * 4.18 J/g°C * 3.0°C. The heat absorbed by the water is 188.1 Joules.
Why does water stay cooler than land?
Water has a higher specific heat capacity than land, meaning it can absorb and store more heat before its temperature rises. Additionally, water is a better conductor of heat than land, so it can distribute heat more evenly. This is why water tends to stay cooler than land during hot weather.
What is the best conductor of heat between air water wood and glass?
Air at sea level has a specific heat of 1.0035 kJ/(kg*K). Air at room temperature has a specific heat of 1.012 kJ/(kg*K) Water at room temperature has a specific heat of 4.184 kJ/(kg*K) Therefore, since it takes more energy to increase the temperature of one kilogram of water (because it has a higher specific heat), water is a better insulator. This explains (roughly, though it is much more complex when taking in actual mass, size, and radiation) why on a hot day the air temperature will change much more than the temperature of a pool of water.
What does it mean to say that the specific heat capacity of water is greater than that of iron?
It means that water requires more energy to increase its temperature compared to iron when the same amount of heat is applied. This is because water has a higher specific heat capacity, which reflects its ability to store heat energy more efficiently.
