If 50 grams of a substance with a temp of 20 degree Celsius and specific heat of 2 is mixed with 200 grams of water with a temperature of 40 degree Celsius what will be the equilibrium temperature of?
Heat gained by one object has to equal the heat lost by the other object. The final temperature of the two objects will be the same.Object 1:mass1 = 50 ginitial T1 = 20 oCCg = 2 J/degree/gramfinal T1 = TfChange in temperature = Tf - T1Q = Cg x change in T x mass= 2 x ( Tf - T1 ) x 50Water:Mass = 200 gCg = 4.18 J/ degree/ gramChange in T = Tf - 40Q = 4.18 x (Tf - 40) x 2004.18 x (Tf - 40) x 200 = -(2 x ( Tf - 20 ) x 50)Tf = 37.9 oC
How do you find how much heat is gained in a specific heat problem?
q = C x m x (Tf-Ti), where q is heat, C is specific heat capacity, m is mass in grams, and (Tf-Ti) is change in temperature.
Are the freezing water at 32 degrees Fahrenheit the same as 0 degree centigrade?
Yes. we can convert Fahrenheit values to centigrade values and vice versa by the following formula: TC=(TF-32) X 5/9 where TC :Temperature in centigrade TF :Temperature in Fahrenheit
What heat is absorbed or released when a substance changes states?
absorbed: endothermic released: exothermic however, substances rarely do this when changing state ()i.e solid to liquid etc() but it is common in chemical reactions ()Lithium+water for example()
How many calories of heat energy are required to melt 10 grams of ice?
q = m x C x ΔT q = amount of heat energy gained or lost in calories m = mass of substance (in this case water) in grams = 10g C = heat capacity of substance (in this case water) = 1cal/gram•oC Tf = final temperature = 32 oC Ti = initial temperature = 0 oC ΔT = (Tf - Ti) = 32 oC q = 10g x 1cal/gram•oC x 32 oC = 320 calories

How is centigrade translated to Fahrenheit?
Tf = 1.8 x (Tc+32) Tf = temp in Fahrenheit Tc = temp in centigrade
Will a SD card work in a TF slot?
Yes, but only Micro SD cards will fit in the TF slot
Can you put a sim card inside where the TF card is suppose to be and it will work?
A TF card is a memory card and is not the same as a SIM card.

If a 50 foot pipe needs a 2 percent grade what is the difference in elevation?
2% grade is equal to 1/4" per foot or 1:50(metric)If you know the length and the grade and need the total fall:TF=l x g:. TF = 50' x 1/4"per foot (or 0.25)TF = 12.5" or 12'-6"To find the grade:g = TF / lTo find the length:l = TF / g
