Question

Suppose that a cup of soup cooled from 90C to 50C after 25 minutes in a room whose temperature was 20C. Use Newton's law of cooling to answer the following questions.

a. How much longer would it take the soup to cool to 30C? (in minutes)

b. Instead of being left to stand in the room, the cup of 90C soup is put in the freezer whose temperature is -15C. How long will it take the soup to cool from 90C to 30C?

Answer #1

A loaf of bread is removed from an oven at 350◦F and cooled in a
room whosetemperature is 70◦F. If the bread cools to 210◦F in 20
minutes, how much longer willit take the bread to cool to
150◦F.

A plate is removed from an oven at temperature of 50◦C and
placed in a large room at 20◦C . After 5 minutes the temperature of
the plate is 40◦C . How much longer will it take to reach 30◦ ?
So far I think I have only learnt about Newton's Law of Cooling,
so if the answer could be relative to that formula that would be
helpful in my understanding.

Water is boiled and is put to cool. The temperature of the air
in the room is rising linearly in relation to the function
T(t)=30+0.01t, where t is minutes and T is Celsius. Suppose this
satisfies Newton's Law of Cooling: the change of temperature of the
water is proportional to the difference of the water temperature
and the room’s ambient temperature. We take the water's temperature
10 minutes after and find that it's 81*C. Graph and explain T.

Suppose you should make tea and that you pour 3.4dl of boiling
water into a cup. You want to drink your tea at a temperature of 55
° C and therefore plan to put ice cubes in the boiling water so
that the temperature is right. You take ice cubes from the freezer
where the temperature is 18 ° C. The ice cubes weigh 15 g. How many
ice cubes should you put in your tea water? Suppose the teacup...

Newton's Law of Cooling tells us that the rate of change of the
temperature of an object is proportional to the temperature
difference between the object and its surroundings. This can be
modeled by the differential equation dTdt=k(T−A)dTdt=k(T-A), where
TT is the temperature of the object after tt units of time have
passed, AA is the ambient temperature of the object's surroundings,
and kk is a constant of proportionality.

Newton's law of cooling/heating states that the time
rate of change of temperature of a cooling/heating object is
proportional to the difference between the temperature of the
object and the ambient temperature of the medium where the object
resides.
If we let Ta represent the ambient temperature and T represent
the temperature of the object then a DE representing this situation
is
dT/dt=k(T−Ta)
where k<0.

CASE PROBLEM 4A: Katrina Wants Relief from the Open-Office
Plan.
Katrina has been working as a business development planner at Gold
Medal, a telecommunications company, for three years. Gold Medal
sells telephone and Internet services to residential and commercial
customers. Considering that the telecommunications business is
intensely competitive, business development is essential to Gold
Medal. Another reason that business development is essential at
Gold Medal is that large numbers of customers are dropping their
landline telephones and shifting to mobile....

Liebeck v. McDonalds Restaurants: The Original Coffee Product
Liability Case James M. Dedman, IV Back in 1994, Stella Liebeck v.
McDonalds Restaurants became one of the most talked about lawsuits
in American history. To this day, that New Mexico state court case
is an essential component of any tort reform debate or discussion
of litigation lore. At that time, and to this day, the thought of a
