Physics assignment! please help!?

1) the hottest temperature on a planet was 864 degree Fahrenheit recorded on Venus by the Soviet venera probe and the US pioneer Probe. The coldest place in the solar system is Pluto where the temperature is estimated at -360 degree fahrenheit. CALCULATE each of the temperature in degree Celsius.



2) The temperature of background radiation left over from big bang during the creation at the universe is 3 K (kelvin). What is the temperature of the universe in Fahrenheit and Celsius?



3) bradley, working in his 23 degree celsius kitchen, is cooking himself a crepe in an iron skillet that has a circular bottom with diameter of 30 cm. how hot must the skillet be in order for Bradley to make a 710.3 square cm crepe that just fill the bottom of the pan?



4) phoebe's insulated foam cup is filled with 0.150 kg of the coffee (mostly water) that is too hot to drink, so she adds 0.010 kg of milk at 5.0 degree celsius. if the coffee has an initial temperature of 70 degree celsius and the specific heat capacity of milk is 3800 J/kg, how hot is the coffee after the milk is added?



5) While Laurie is boiling water to cook spaghetti, the phone rings, and all 1.5 kg of water boils away duing her conversation. if the water was initially at 150 degree celsius, how much heat must have been gained for all of it to turn into water vapor? (Hv water = 2.26 x 10 (to the 6th power) j/kg



6) By january, the 3.0 kg of water in the birdbath in Daniel's backyard has frozen to a temperature at -7 degree celsius. as thje season changes how much heat must be added to water to make it confortable 25 degree celsius for the birds?



THANK YOU SO MUCH! :)Physics assignment! please help!?
The conversion of fahrenheit to celsius is



C=(F-32)/1.8



So 864=462.22

and -360=-217.78



Celsius to Kelvin formula is



K=C + 273



Hope this helps you figure some of them out. Just google your question and it may help you more than this site.
