Acooper object that can be modeled as cube with 10 cm edges is soaking at uniform temperature of 260 c. it was suddenly placed in an environment maintained at 35 c and having heat transfer coefficient h=20 w/m2. c. the properties of the copper are as follows: rho = 8900 kg/m^3, cp=0.38 kj/kg. °c, and k=370 w/m-c. a)- calculate the time required for the center temperature to reach 90°c. b)-calculate the total heat transfer over the time period required for the center temperature to become 90°c.

can you make it more obvious. i can't see it properly

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only
