Question statement

{mass_string} of {Mat_string} is heated from {st_string} to {et_string}, changing in temperature and phase.

{if(switcharoo=1,twostep(),onestep())}

	Solid specific heat	Latent Heat of fusion	Liquid specific heat	Latent Heat of vapourisation	Gaseous specific heat	Fusion Temperature	Vaporisation Temperature
{Mat_string}	{solid_heatcap} JK<sup>-1</sup>kg<sup>-1</sup>	{phase1_latentheat} Jkg<sup>-1</sup>	{liquid_heatcap} JK<sup>-1</sup>kg<sup>-1</sup>	{phase2_latentheat} Jkg<sup>-1</sup>	{gas_heatcap} JK<sup>-1</sup>kg<sup>-1</sup>	{phase1_temp} K	{phase2_temp} K
