Answer:
Q = 768.47 J
Explanation:
Given that,
Mass of the metal, m = 25 g
Initial temperature, T₁ = 21.0 ºC
Final temperature, T₂ = 80.0 ºC
The specific heat of the metal is 0.521 J/gºC.
We know that the heat released due to the change in temperature is given by :
Hence, 768.47 J of heat energy will be needed.
38K
-391°F
Explanation:
Given temperature:
Temperature of Triton = -235°C
Unknown:
Surface temperature of Triton in °F and Kelvin
Solution:
Temperature is the degree of hotness or coldness of a body.
It is usually measured using units of kelvin, degree Celsius and degree Fahrenheit.
tK = 273 + t°C from °C to K
t°F = t°C + 32
tk = temperature in kelvin
t°C = temperature in Celsius
t°F = temperature in Fahrenheit
tK = 273 + (-235) = 38K
t°F = x (-235) + 32 = -423 + 32 = -391°F
