What is the temperature of a star whose maximum light is entitled at a wavelength of 290nm?
The temperature of a star can be calculated using Wien's law. Given the peak wavelength of 290nm, we can use the formula λmax = b/T, where b is a constant (2.898 x 10^-3 m K) to find the temperature of the star. In this case, the temperature would be approximately 10,000 K.
The peak intensity of radiation from Star Beta is 350 nm What is the average surface temperature of Star Beta rounded to the nearest whole number?
To find the average surface temperature of Star Beta using its peak intensity wavelength of 350 nm, we can use Wien's Law, which states that the peak wavelength (in meters) is inversely proportional to the temperature (in Kelvin). The formula is given by ( T = \frac{b}{\lambda} ), where ( b ) is Wien's displacement constant (approximately ( 2.898 \times 10^{-3} ) m·K). Converting 350 nm to meters gives us ( 3.5 \times 10^{-7} ) m. Plugging in the values, we find that the temperature ( T ) is approximately 8285 K, which rounds to 8285 when expressed as a whole number.
What is the formula for calculating the temperature of a star?
The formula for calculating the temperature of a star is Wien's Law, which is expressed as T = b / λ, where T is the temperature of the star, b is a constant value (approximately 2.898 x 10^-3 m*K), and λ is the peak wavelength of the star's emitted radiation.
The surface temperature of a star can be estimated based on the stars?
One way in which a scientist can determine the surface temperature of a star is by:Step 1: launching a rocket to spaceStep 2: Ensure they have a thermometer with them.Note: The thermometer must be at least 20m long so as to reach the star whilst the scientist remain in the rocketStep 3: After having landed on planet Mars, the scientists open the shuttle of the rocketNote: they must be tied to the rocket so they don't fly out and get stranded/lost in outer space ( there safety must be ensured so that they do not get abducted by aliens)Step 4: The scientists hold out the thermometer towards the nearest star and measure it's temperature in degrees Celsius
What is the temperature of a star whose maximum light is emitted at a wavelength of 800 nm?
To find the temperature of a star based on the wavelength of maximum light emission, we can use Wien's displacement law, which states that the wavelength of maximum emission (( \lambda_{max} )) is inversely proportional to the temperature (T) in Kelvin. The formula is ( T = \frac{b}{\lambda_{max}} ), where ( b ) is Wien's displacement constant, approximately ( 2.898 \times 10^{-3} , \text{m} \cdot \text{K} ). For a wavelength of 800 nm (or ( 800 \times 10^{-9} ) m), the temperature is roughly ( T \approx \frac{2.898 \times 10^{-3}}{800 \times 10^{-9}} \approx 3622.5 , \text{K} ). Thus, the star has a temperature of about 3623 K.
How long does it take to freeze 450 milileter of water in a freezer?
The amount of time it would take to freeze a 400Ml bottle of water will depend on the temperature of the freezer. On average this takes about 3 to 5 hours.
What is the ideal fridge and freezer temperature for food storage?
The ideal temperature for a fridge is 37-40F (3-4C) and for a freezer is 0F (-18C) for safe food storage.
What are the recommended refrigerator and freezer temperature settings for optimal food storage?
The recommended refrigerator temperature is 37-40F (3-4C) and the recommended freezer temperature is 0F (-18C) for optimal food storage.
What is the recommended fridge and freezer temperature for optimal food storage?
The recommended temperature for a fridge is 37-40F (3-4C) and for a freezer is 0F (-18C) for optimal food storage.
What is the normal fridge freezer temperature and how can it be maintained for optimal food storage?
The normal fridge freezer temperature is around 0F (-18C) for the freezer and 37-40F (3-4C) for the fridge. To maintain optimal food storage, keep the fridge freezer temperature consistent by not overloading it, ensuring proper air circulation, and regularly cleaning the coils to prevent dust buildup.
What is the recommended temperature for both the freezer and fridge?
The recommended temperature for a freezer is 0 degrees Fahrenheit (-18 degrees Celsius), and for a fridge, it is 37-40 degrees Fahrenheit (3-4 degrees Celsius).
What are the recommended temperature settings for both the fridge and freezer to ensure optimal food storage?
The recommended temperature setting for a fridge is 37-40F (3-4C) and for a freezer is 0F (-18C) to ensure optimal food storage.
What are the recommended fridge and freezer temperatures for optimal food storage?
The recommended temperature for a fridge is 37-40F (3-4C) and for a freezer is 0F (-18C) for optimal food storage.
How do you set temp on GE fridge and freezer?
To set the temperature on a GE refrigerator and freezer, locate the temperature control dial or digital display inside the fridge compartment. For most models, turning the dial to a higher number will lower the temperature, while a lower number will raise it. If your model has a digital display, press the temperature setting button to adjust the desired temperature for both the fridge and freezer compartments. Recommended settings are typically around 37°F (3°C) for the fridge and 0°F (-18°C) for the freezer.
What is the best temperature for both the refrigerator and freezer to ensure optimal food storage and preservation?
The best temperature for a refrigerator is around 37-40F (3-4C) and for a freezer is around 0F (-18C) to ensure optimal food storage and preservation.
How long can an apple pie last not cooked in freezer?
If you have wrapped it very well to avoid freezer burn, you may get 3 to 6 months of storage time. This can depend on temperature, how often the freezer is opened and closed, it's location in the freezer, and unexpected power outages. A deep freeze is typically the best place to store items for freezing as it's not opened as frequently as one with your fridge, and tends to hold a constant temperature.
How long does it take ice cubes to freeze?
Depends on the starting temperature of the liquid being frozen, the melting point of the liquid being frozen, and the temperature of the freezer being used to freeze the liquid. Of course it depends upon the temperature of the water being placed in the ice trays, and the temperature of the freezer into which the trays are placed ... but mine, room-temp tap water into a stack of 4 ice trays ... about 10 hours.
