If I accidentally dropped my cooked steak off the deck into the snow, how much snow could it melt? Recall that for H,0, L, = 3.33 × 10° L, = 22.6 x 10° , and c = 4186 (not all values needed) b If instead I accidentally dropped my cooked steak in a bucket with 0.15 kg of snow (which instantly became sealed to the environment), what temperature would the steak reach?

#7. Suppose I am outside grilling on a 0 °C day. I grill a 0.64 kg steak for 7.0 min. Suppose
my grill can transfer heat to my steak at 330 !. How do I like my steaks cooked? You
can assume that although starting at 0 °C and composed mostly of water, there is no phase
change for the steak. Note that the specific heat capacity for steak is 3490 e. Also note
that a rare steak is cooked to above 130 °F, a meadium-rare steak is cooked to above 140 °F,
a medium steak is cooked to above 150 °F, a medium-well steak is cooked to above 160 °F,
and a well-done steak is cooked to above 165 °F.
we will solve this by basic calorimetry , once we get the final temperature we can guess the type of stake
e = (T; – r;)
Q = heat transferred
m c
= 330 * 60 * 7
m = mass of steak = 0. 64
c = 3490
T = final temp ?
= initial temp = 0
Ti
+ T;
Ts
me
330 *60*7
+ 0 = T;
62. 05229 celcius = 143. 694122 fahrenheit
0.64 * 3490
so it is medium rare
