Estimate the temperature change you expect in this air. Let the volume of your room be 38 m³. Heat capacity of air is 1000 J/kg .° C.

3. A glass flask whose volume is 1000.00 cm³ at 0.0°C is completely filled with mercury at this temper- ature. When the flask and the mercury are warmed to 55.0°C, 8.95 cm³ of mercury overflow. If the coefficient of volume expansion of mercury is 18.0 x 105 K-1, what is the coefficient of expansion of the glass?

500ml of 60oC water at is added to a beaker. Water’s specific heat is 4.186 J/g °C.  You have 40ml of and unknown substance that you add to the same beaker. The unknown substance’s specific heat is 14.3/goC  The final temperature of the beaker is 45oC. What was the initial temperature of the unknown substance?

What is the change in length in millimeters of a 3.00-cm-long column of mercury if its temperature changes from 29.0°C to 43.0°C, assuming the mercury is unconstrained lengthwise? mm

An iron rod with an initial length of 13.65 m has its temperature raise from 10°C to 31.74°C. If an iron has a coefficient of thermal expansion of 12 times Fr..10 to 6th power 1/Celsius what is the changing in the length of the rod?

Question 4If a copper kettle has a base of thickness 2 mm and area 3 x 10^-2 m², estimate the steady difference in temperature between inner and outer surfaces of the base which must be maintained to enable enough heat to pass through so that the temperature of 1 kg of water rises at the rate of 0.25 K s^-1. Assume that there are no heat losses, the thermal conductivity of copper = 380 Wm^-1K^-1. and the specific heat capacity of water is 4200 Jkg^-1 K^-1.

You accidentally left a jar with a 674g brass lid outside in the snow, dropping it to a temperature of -33.87°C. To warm it up gently, you put it into a 1.27L water bath. After the 5 minutes, the final temperature is 80.66° C. What was the original temperature of the water? °C. No units are required (since it's hard to write °C)

FOLLOWING CONSTANTS ARE GIVEN FOR CALCULATIONS. Specific Heat of Water = 4186 J/kg °C, Specific Heat of Iron = 452 J /kg °C, Specific Heat of Ice = 2093 J/kg °C, Specific Heat of Lead = 130 J/kg °C Latent Heat of Fusion = 3.34 x 105 J/kg, Specific Heat of Copper = 385.1J /kg.'C Density of iron = 7.874 g /cm3 Density of copper = 8.95 g /cm3 3. 5 kg of ice at 0 °C is mixed with 1.5 kg of steam at 100 °C. Calculate the final temperature of the mixture.

A 12 m by 4.2 m concrete wall has the thickness 8.2 cm. Find the heating rate through this wall if one side of the wall is at 36 C and the other side is at 28°C. The thermal conductivity of this concrete wall is 1.0 W/m-K.

How much thermal energy (in J) is required to boil 3.00 kg of water at 100.0°C into steam at 151.0°C? The latent heat of vaporization of water is 2.26 x 10° J/kg and the specific heat of steam is 2010 kg.°C HINT Need Help? Read It
