- At "low" temperatures, the heat capacity of some materials varies with temperature as 3 12π¹ NkB T C (T) ² (£) ². 5 Here N is the number of atoms, kB is Boltzmann's constant, and Tp is the "Debye temperature," which is different for different materials. For example, 2300 K for diamond, which is particularly high. TD = How much energy would it take to raise the temperature of one mole of diamond from 100 K to 300K? O 150 Joules. 60 Joules. O 319 joules. O 630 Joules.The amount of radiant energy emitted by a surface is given by q = ɛ0 AT+ where q represents the rate of thermal energy (per unit time) emitted by the surface in watts; e = the emissivity of the surface 0<ɛ<1 and is unitless o = Stefan-Boltzman constant (o = 5.67×10% ) A represents the area of the surface in m² Ty = surface temperature of the object expressed in kelvin What are the appropriate units for o if the equation is to be homogeneous in units?A block of ice (m = 13 kg) at a temperature of T= 0 degrees C is placed out in the sun until it melts, and the temperature of the resulting water rises to T,= 26 degrees C. Recall that the specific heat of water is c = 4186 J/(kg-K), and its latent heat of fusion is Lf= 3.34 × 10° J/kg. Input an expression for the amount of energy, Em, needed to melt the ice into water. %3D (b) Input an expression for the total amount of energy, Etot, to melt the ice and then bring the water to T2. Eto1 = || What is this energy in joules? Etot
- If the temperature of an object goes from 500 K to 9500 K, By what factor is its energy emitted per second increased?Some amount of heat energy is removed from a 11cm X 14cm X 10cm block of ice to cool from 0ºC to -22ºC. (Hint: to find mass, use the relation between, density, mass and volume) ((a*2)+(b*1)+(c*2) Calculate the following: a) The mas of ice cube in grams (density of ice = 920 kg/m3). b) The temperature difference in kelvin c) The energy removed from ice in calories (specific heat of ice = 2093 J/kgºC)A scientist recorded the temperature of a freshwater lake at 9am and it was 18 C. She has already calculated the mass of the water in the lake to 500 kg. She expects the change in thermal energy by 6pm to be roughly 12,500 J. If that is true, what should the temperature of the lake be when she measures it again at 6pm?
- The average temperature of the atmosphere has increased by 0.4°C over the last thirty years. Estimate how much energy has gone into warming up the planet in this way. Keep in mind that the atmosphere has a mass of 5 × 1018kg, and the specific heat capacity of air is about 1 Jg−1K−1. How do we get to this answer (2×1021J)The Earth is spherical in shape and can be considered to be a perfect black body radiator at a temperature of 53°C. Radius of Earth is 6350 km. (consider: Stefan's constant o = 5.67 x 10 W/m?T4) 8 Calculate the total power radiated from the Earth in WattsAssume that when in thermal equilibrium (i.e. the temperature is not changing) Mars absorbs all of the heat it receives from the Sun and then re-radiates it as black body radiation from all parts of its spherical surface. Assuming that Mars' temperature is uniform across all of its surface, calculate the temperature on Mars. The Stefan-Boltzmann constant σ=5.7×10−8 W m−2K−4.To answer this question you need to balance the total energy per second being absorbed by Mars with the total energy per second being radiated by Mars. Key: Flux of radiation from the Sun at Mars' orbital radius is 597 W m-2. The luminosity of the Sun Ls = 3.8×1026 W. Mars orbits at a distance of 2.25×1011 m (1.5 AU) from the Sun. Total amount of radiative energy per second is 2.2 x 1016 W.
- A hollow box with an opening of 1 cm2 area is heated electrically. How much is energy is emitted per second if the temperature is 1600K? [answer is 37.2 x 104 J/m2s]The amount of heat required to convert ice at -8∘∘C to water at 53∘∘C is 23 kJ. Calculate the mass (in g) of the ice that is converted to water. The specific heat capacity of liquid water is 4186 J kg-1 K-1, the latent heat of fusion of water is 3.34 ×× 105 J kg-1, and the specific heat capacity of ice is 2100 J kg-1 K-1.(W/m), in Santa solar radiation into energy- solar radiation (w/m?) 400 300 200 100 time (hrs past midnight) 4 8 12 16 20 ot dengndi lo
