Answer:
D
Explanation:
Drilling through the earth to reach areas hot enough to create steam is difficult because the drill can break down deu to hardness of the rocks
Explanation:
The given data is as follows.
= 2 L, = 3 L,
= X, = 0.1 X,
= 4.8 g, = 0.36 g,
= ?, = ?
According to the ideal gas equation,
= 2
or,
Thus, we can conclude that two gases does not have the same molar mass and flask 1 contains a gas of higher molar mass.
Answer:
Commonly available heat-storage materials cannot usually store the energy for a prolonged period. If a solid material could conserve the accumulated thermal energy, then its heat-storage application potential is considerably widened. Here we report a phase transition material that can conserve the latent heat energy in a wide temperature range, T<530 K and release the heat energy on the application of pressure. This material is stripe-type lambda-trititanium pentoxide, λ-Ti3O5, which exhibits a solid–solid phase transition to beta-trititanium pentoxide, β-Ti3O5. The pressure for conversion is extremely small, only 600 bar (60 MPa) at ambient temperature, and the accumulated heat energy is surprisingly large (230 kJ L−1). Conversely, the pressure-produced beta-trititanium pentoxide transforms to lambda-trititanium pentoxide by heat, light or electric current. That is, the present system exhibits pressure-and-heat, pressure-and-light and pressure-and-current reversible phase transitions. The material may be useful for heat storage, as well as in sensor and switching memory device applications.
